Game Demos - Do You Try Them?

Tell us your thoughts on the usefulness of game demos.

I play the demo of a game only if I don't feel like buying it/can't afford it/etc. I guess everyone else does that, too. XD

I wouldnt say that. Sometimes think you might like a game but you're not sure. A demo would tell you whether you'll buy it or not.

I always get the demo first, if available, and play it before buying the game.
