HijacK: The original was a console exclusive. Between the release of the first and the release of the sequel, there is a gap of more than enough years to label the effort of porting the game not worth while considering the first wasn't a huge success and most PC user base wasn't interested in it, mainly because of the age. This being said, I can't say I'm sad the first one is still exclusive due to still being 1 of many reasons I own my consoles. In other words - exclusives, whether they are brand exclusives or multi console exclusives.
Fever_Discordia: Yeah, but even if you DO have it on console then you're still just using a game controller to play an FPS! EUGH - like trying to put together a 1000 piece jigsaw wearing mittens!
I don't see a problem with a controller for an FPS. As a matter of fact, I for one enjoy FPSs a lot more with the controller. Exceptions to this are game that were not designed to locking in sight like Left 4 Dead and Counter Strike.
