I'm sorry to say it but I haven't played a lot of the games I think would make it to my list. The Witcher series, the new Deus Ex, Red Dead Redemption possibly, Far Cry 3... Also, I tried to order them by how much fun playing them was, not by how good they are. The first Assassin's Creed isn't a great game, but I did enjoy playing it a lot - much more than playing the other games in the series - mainly due to its atmosphere and Altaïr.

I'm bumping because I won't get in trouble for it.

It is mind blowing to me that Borderlands 2 is looking like it won't make the top 25.

:D  Woo, im not the only one who has bumped now xD

Anytime you need it.

Yes, this is another bump.
