1vs1 seems like the simplest way to have a tournament that's longer than a few hours (at least if we don't do all matches at once
).
So basically everyone plays 1vs1 against each other twice as part of qualifications and then qualified among them (2 thirds basically) proceed into the final tournament per single or double elimination tournament.
For example if we have 10 players we can split them into two qualification groups of 5 players. Every player plays the rest of the four twice, so we end up having 20 matches for each group: total of 40 matches.
The results of these matches (winning, losing or a forfeit) is rated according to this points system:

So finally we have a two top 5 lists of which bottom two are disqualified and top three proceed into the 6-player tournament.
Of course, we can adjust this number if we have 12 players. In that case groups could be of 6 and then we just have to decide whether to disqualify 3 or 2 of them.
If it's only 2 then the tournament would be 8-player one.
