Game costs are pretty much equal, so if you are going to get it for just 1 game, and you are not as a general rule a "console" gamer with excess disposable income, then No.
If however, you were going to be getting a blue ray player anyway, assuming you don't already have one, then Yes.
If you are debating between the XBOX360 and PS3: Consider that while the game selection is good, the XBOX360, is returned on average something like 2.1 times due to it getting completely fubared for one reason or another. And just like it's predecessor the XBOX, the cheap #$$ DVD player will fail at or about a year depending on usage.
I also don't know anyone with a PS3 that regrets the purchase. However, I suppose you might be a first if all you have is XBOX360 friends because you can't get online together or share games.
