Everyone loves to be blown away by astonishing high quality graphics, but playability is the heart of the game.
The best games are always ones you play with a bunch of your mates in a room. Graphics is always secondary to that, for me.
Despite Tekken and many subsequent posh 3D beat 'em ups, Street Fighter II is still the most FUN! I normally destroy anyone who takes me on, then retire after 4 rounds with huge ragged blisters where my thumbtips were. I then can't play anything for weeks.
Oh yeah, you gotta love the violence!
If you want paranoia and frenzied bursts of sickening violence, Alien v Predator isn't bad.
