I dunno guys - I thoroughly enjoyed this game. Some things bothered me too , but then there's always something wrong with every game isn't there
One thing that got to me was that once you got the Ant Lion "gun" you could only use it in predefined places - stupid. And the ending was a little too abrupt for my tastes - still - graphics are very good - and much better than the claustrophobic feel of Doom 3 in my opinion. They're colourfull and very realistic. They also could have used more vehicles in the game, although the ones they have are loads of fun. Although you might be right about the story not being as good as the first one, but that always kinda happens with sequels anyway - plus the story's not really finished so who knows.,
Plus - STEAM sucks balls! The game has definitely got the worst installation procedure of all time, and if more games employ it, it will be the demise of PC gaming.
