I would pick Killzone 2 for most of people,because I think most have heard it and seen it.It sells itself with graphics.
Games like Uncharted etc are not well known...
Mgs 4 in the other hand would be second choise..
LBP never..well maybe if I could show at youtube what it is..

My response: "Why would you not want a PS3?"

-- Plays most HD games (crossplats)
-- Has an awesome library of exclusives
-- is a Blu-Ray player
-- is a phenominal audio device, better than pro CD players that cost more, honestly.
-- works as a browser on your TV
-- upscales DVDs better than most upscaling players (and better than certain other consoles, IMO)
-- Plays Playstation 1 games

...the list goes on and on.

casue the others suck, thats why.
