The last game I played was 'WOW' or 'Crysis' the latter was German and technically excellent, very enjoyable, actually...I like visceral entertainment. I can't get into thumb control and prefer the mouse for looking around. 'Halo' (MS) was the first game I played against online opponents and is the style of game I like. I get my name from the ironic use of the word 'dirt'.
Aside : BTW, playing those FPSs is an excellent way of improving your aim with a real gun, IMO.
