I like left4dead zombie theme games and survival games like tomb raider too
Can't deny tho GTA is awesome
Also like story line games too like the arcana and such!
Oh, I'll pick GTA easily, as long as it's the online version. Left 4 Dead 2 is also quite fun, if you have friends... But you'll generally have more playtime with GTA.
I don't know how Tomb Raider can't be the best game, but we all have our preferences.
It's both a story, adventure and a great rpg that is super fast passed. The free world of GTA is funny sometimes tho. Hard choice, but Tomb Raider all the way.
