I agree with you, I also think it's weird making a "top 25" list for a current system. If it was a "25 360 games you must own" list, that would be acceptable
Anyway, I think they stretched the list a bit. A few titles just seem there to fill the 25 spots.
And one thing that disappointed me was MW2 being lower than COD4. Yes, it maybe shouldn't even be on the list, but seeing that it is, and lower than COD4, I'm starting to think my excitement for the game may be a bit high. I hope the multiplayer's as good as the first.. (although I'm guessing it's because the single player's too short and stuff)
