crysis 2,deus ex human revolution,halo 3,assasins creed 1 or quantum of solace?

Halo 3 is better. Halo 3 is one of the best games ever made and the other games you've mentioned are not one of the best games ever made. Halo 3 has great graphics and it has better gameplay and the gameplay is very entertaining and very enjoyable and the gameplay is better than the other games you've mentioned and the storyline is better in Halo 3.

Halo 3 pros: It has awesome multiplayer mode and the gameplay is awesome and the storyline is awesome as well

Halo 3 cons: The multiplayer can get repetitive and the framerate can drop

Assassin's Creed pros: It has awesome and beautiful graphics and the gameplay is good and the storyline is pretty good

Assassin's Creed cons: The single-player experience can get repetitive and the missions can get repetitive

Deus Ex: Human Revolution pros: It has awesome gameplay and the storyline is awesome too and the design and presentation are really good

Deus Ex: Human Revolution cons: The framerate can drop and the missions can get repetitive at times

Quantum Of Solace pros: The gameplay is pretty good

Quantum Of Solace cons: The gameplay can get repetitive and the graphics are just not too good and the single-player experience can get repetitive

Uh, that's a lot of games. I would have to say Deus Ex: Human Revolution because (in my opinion) it has the best story, and it has the best moral decisions (pro and cons system). Crysis 2 has the better graphics out of all of those, however.
