" Star Wars KOTOR 1+2, Fable, Timesplitters 1+2, The F1 games, Star Wars Battlefront, Grand Theft Auto."
Ok lets see
KOTOR was made by Bioware whom released Mass Effect 1 + 2 (soon) on Xbox 360.
Fable 2 is out, Fable 3 next year
F1 games = no idea sorry
Star wars = no idea sorry
Timesplitters = the Xbox 360 has the best lineup of exclusive shooter/western rpg content.
Xbox 360 GTA IV has two exclusive episodes and higher framerate (which is a killer in this game)
Xbox Live is the best online service this generation and its fully integrated into every game. It has lower latency connections (my personal experience vs PSN playing people in Europe from New Zealand), it has better matchmaking, its more stable, its moderated to prevent cheaters/lamers ruining your games, all games have demos on that fantastic Xbox Live service whilst on PSN its a crapshoot, also you DONT HAVE ANNOYING LONG AND SLOW UPDATES more than once a month almost PMS like clockwork.
Also Xbox 360s are cheaper in Australia vs the PS3. You can grab an Xbox 360 Elite + 2-3 great games for the price of a PS3. The price of Live is worth it if you want to play online and since you don't want Blu Ray and like the Xbox 360 games it does make it seem like a more compelling choice.
Tease.
