Personally, I would not. Reason: as a game developer, I need to eat. I don't have faith that I can or will soon be able to trade bitcoins for food, housing, and other items that I need. This could reflect my own lack of knowledge or vision, or could mean that I'm part of the problem, or all of the above.

Google "bitcoin market" - they are quite fungible, for now. There's really very little risk in accepting them, as long as you don't hold them.

That said, how many people will try to pay you with them?

Bitcoins could be embedded in the game. The players would start out getting very small sums as actual in-game rewards, so it'd look like just a regular in-game currency at first. Then later they'd notice that a much bigger sum of bitcoins (say, 3$ worth instead of 0.1 cents worth) can buy more game content, and they'd be nudged towards out-of-game means for getting them.
