And please only vote in one of the two polls, I've only split them because the boad did not let me create one huge poll.
The other poll is here:

If the vote goes to the gods, we'll decide later which ones we take first. The original submission was only for Greek gods.
I'd have added Muslim/Jewish/Christian gods, but there are so few of them

Hindu gods are plenty, but considering the number of Hindus around who may get offended, maybe they're not a good idea.
Edit: the NOP option, stick to numbers, is in the first poll.
