Well, my taste in videogames is usually not mainstream, so I will pick the following as my favorite game of 2002 and beyond:
SERIOUS SAM 2 !!!
I find this game very funny and addictive, I just love it!
Other games:
WORMS 4 MAYHEM
HALF-LIFE 2
PARIAH
AGE OF MYTHOLOGY
FAREHNEIT (not sure if I have spelled it correctly)
ARMIES OF EXIGO
Ok, you can flame me now and say that my choices suck, I will endure it...
