There are plenty of games that are better after a few drinks, but I can't think of any other that literally require you to have one in your hand while playing in order for the thing to work.

Corona Beach Volleyball does. The advergame from the beer label will only launch if it detects a Corona bottle sitting on the table, after which it'll generate a little beach volleyball court and some palm trees.

It's cute, but also a little annoying; I didn't have any Corona in the fridge to try it out with, and I'm not going to rush out and buy some just to play some cheap iPhone game.

If you do, though, have at it.
