RE 6 was horrible (Besides Leon's campiagn...I guess.) They literally destroyed the whole series this game was laughable with zombies having guns. I'm long time fan since like 1st grade watching my friend's brothers play the 1st and 2nd game. RE 4 was so well done but seriosuly 6 was just laughable. I have faith for evil within though (new game from RE 1 creator)

Go do so, this game is pretty good so far I bought it for like $20 from Xbox live marketplace. It's challenging on normal and I'm just on the 3rd level. Also Deux Ex Human Revoultuion is good too.

Something like Deus Ex human revolution or Silent Hill 2. Is Crysis 1 any good? The Orange Box? 

Wait how is it different from instincts? Cuz the story was horrible for that game

I loved RE so much but 6 was kinda well dumb. I already have left 4 dead and RE 4.

Should I go with Silent Hill HD, Dead island, dead rising 2? Any other good ones?
