There has long been debate over this what is better a console FPS such as (Half-Life 2 on Original) Vs PC FPS (Half-Life 2).

With a FPS on a console you use the controller now to aim and move around and use triggers to show but with the FPS on PC you can use a  mouse which i personally think its easier to precision aim on someones head (for an awsum kill btw) and use the keyboard to move around and i feel like i have more freedom like that.

With Half Life 2 on the original xbox there was a bad framerate because the console didnt seem to be able to handle the game that well so it was laggy and unplayable.

On the overhand i played it on my PC which has pretty good specs i played it lag free (except when i blew up heaps of explosives and grenades in one spot) and got through the whole game with a quite enjoyable few hours.

Although this might not be the same case now with the new pc games which have more demanding specs then what older games did competing with the awsum power of the xbox 360 but overall i personally think that PC FPS shooters are my favo to play but i might not be able to play them for much longer because i would have to upgrade my computer each month but thank god i have the 360.
