I've decided to go for most influential player with my top 10, with explanations to follow, just to see what I can come up with (still haven't thought of all the players/ranks by the time I'm typing this). Also, I can only speak for the last half of the year, since I pretty much (re)started playing exactly half way through the year (4th of June?). Note, I did the top 5 improved first, and now I've run out of time for the top 5 influential, so I'll leave the top 5, and come back to do the rest of the 10 later. I'll leave the initials though, wonder if people will guess who they are.
1. Woned.
Centre ability, attack ability, charisma, fame, youth, this tronner has it all. I hate comming up against woned when I'm centre, even if he isn't trying. And I hate it even more when I try to block centre as defence, since he'll stay alive even in tiny little spaces. Not many people appreciate it, but woned is very skilled at pretty much every other position on the grid, its just he shines so well as a centre/attacker nobody really notices. He has certainly influenced the way centre/defenders start each round, and even in individual rounds he'll influence the entire style of play.
2. Unk holers.
Although almost every clan or team out there now has a system for no-point holing, and although Unk weren't the first to employ the NPH, they were the first to take it to the next level as far as I'm concerned, and are probably the fastest and most systematic holers out there at the moment. They can sneak past your sweepers and plant a cheeky hole or NPH before you even saw them on your half of the grid. Influence: Sweepers and defenders better keep a watchout for two or more unks gathered in one place. Other teams have also started to realise holing needs a lot more control and professionalism than previously thought.
3. Sine.wav.
Great defender, and overall forter, but thats not why he's here. He is selflessly dedicated to the ladle, and to fortress, especially earlier in the year, he was almost always the one organising brackets, resetting the ladle page, discussing, mediating and helping to decide on the rules, and their implementation. Influence: Behind the scenes, one of the most important (if not the most) figures in fortress, without whom, I'm not sure if ladles would run, and definately much less smoothly than they do already.
4. Titanoboa.
His influence is both in the style of attack, as well as his influence with the Rogues. He pretty much brought them into fortress, and helped garner many of their newer members. Without him, we would probably be without Rogues in fortress, and even if they would have made the jump, they wouldn't be nearly as far along as they are now. His aggressive style of attack is also present, where he is more willing than most to actually try and cut a defender instead of simply relying on holes. Influence: heavy hand in bringing Rogues to become the dominating force of fortress they are, and an aggressive style of attack that keeps defenders on edge.
5. Speeders.
Speeder's reign of domination in fortress is legendary, with the past "3 in a row" a mean feat even the mighty CT has yet to match. They inspire tactics, create some themselves, and retain a very strong squad, which has seen a bolstering recently, with several new applicants. However, their influence also comes with some of the trouble they seem to always find themselves embroiled in on the forums. This year perhaps focused around the use of smurf names in some ladles, which turned into a heated debate. Hardly anyone on the grid at that time wasn't talking about it. Influence: Skill, innovation, but probably most of all, notoriety.
6. Spin
Surprised? I am a little, but Spin has done something pretty amazing with oracle in my opinion. He managed to get a seed on their very first ladle attempt, and then follow it up with a second place finish the very next time. Way to shake things up, and good luck next ladle, defending your number 2 spot!
7. Xyron
Just banging him in here because he's on everyone else's list. Can't fault his mazing ability, watching him is like watching art in progress. As I mention below, he has taken this and brought it to fortress, being probably the second best all-rounder, if not the best, alongside potter. Great defender, fierce attacker, steady sweeper and possibly a rising star in centre (how many do CT need?
8. Deso
Again, although Deso is a strong fortress player, I haven't put him in here for that, but for his impressive organisation skills in the fort world cup and fortress cafe tournaments, as well as the upcomming fortress brawl tournament. He's dedicated himself to these competitions, and to the overall fortress comunity, and put so much effort in, and hardly any recognition. I hope this goes a ways to fixing that!
9. G5
"Want a game of fort?"... "Sure, where should we play?". The answer to this question is, without a doubt, G5's mega fort pro. His server is the cradle of fortress as it is, despite changing its name throughout the year, its stayed true and strong, keeping the riff-raff from playing without logging in, teaching new players about authentication, and a breeding ground for talented fortress players, innovative skill, and amazing battles of fortress ability. G5 maintains this server, tests settings from time to time, and is a great host. Sure if it went, we'd head somewhere else, but while its up, its number 1.
10. Concord
An innovative fortress tactician, skilled player, great mind, and fantastic main writer for the blog
play fortress, where strategy, players, predictions and all else is discussed, mulled over, and brought together. A small but dedicated set of followers and a large number of casual viewers, together a large swathe of the fortress community gets a significant amount of their current news and ideas from this blog. Its a great read from time to time, but delving deeper into the past also lets you explore the fantastic history of fortress. Concord as a writer sticks true to his style and provides riviting features on all aspects, influencing heavily with his words. I would have wished that this top 10 players had been done by him, but it didn't look like it, so I set this up instead.
I also want to do a most improved player, again probably limited to the second half of the year, but I'll only do a top 5 for this:
1. Titanoboa. Despite having played the game for quite a while, he has rapidly improved at fortress this year to be included in almost everyone's top 10. Speaking personally as a defender, titanoboa is one of a handful of players who makes me sit up straight and pay attention when he's nearby my defence, even in a casual game of G5s. However, not only skillwise, he's pretty much led R's transformation from kings of CTF to a serious contender for each and every ladle.
2. Slov. Damn, he'll probably read this, but wow. What an improvement in sumo, and even fort ability. Although he's still not quite near the best, and probably won't be included in any other top 10s, his sumo ability has definately made him someone dangerous to have in your zone, and even just outside it attacking it. With the help of SP, I'm expecting him to go even further next year... unless his career in basketball takes off.
3. Chah. His course is very similar to slov's, with a rapid improvement in sumo, and a slight lag as this transfers into fortress improvement a bit later on. Good mazing ability in sumo often translates to good ability in fortress, and chah is no exception. His talent for centre is another of his many facet's, combined with his 200+ ping (and accompanying ping_rubber), he is a threat to even some of the most talented and experienced centres.
4. Potter. Although he was good when I first saw him, his lengthly practice over the summer has really improved his ability, and turned him into possibly the best all-rounder this game has to offer at the moment and possibly of all time. But unlike many Jack-of-all-trades, he still maintains top tier ability in certain aspects of fortress, especially attack and centre in my opinion.
5. Syre. I've personally seen syre improve from some unknown CTWF noob to a very talented sweeper, and someone who has awareness of what is going on around him on the grid. He has also mastered the transition from passive sweeper to active attacker/holer if the situation of gameplay changes, in a fraction of the time it takes many others. If you are thinking of holing, and you suddenly get a good opportunity, Syre will be there in a snap.
Other honorable mentions: MB53 (who has played more than this guy this year though

), Cronix, Fini, Lanfear, Kult (or whatever name he's using now), and many others I can't remember atm.
