hahahaha am not a fanboy!
i actually had 360 THEN bought a Wii...i really wanted the Wii to be Nintendo's come back
well it kind of was...financially...
but heck why not
1)LA NOIR
2)Gears of War
3)LBP
4)Uncharted
5)Demon"s Soul
7) Heavy Rain

Alan Wake
9)Dead Rising
10) Left 4 Dead
11)Mass Effect
12)Assassin's Creed
and I don't even know what do they have on psn store or the xbox market place
I also made sure to pick EXCLUSIVE and NEW IPS that are specific to this generation only
I know some 360 games are not exclusive as they share it with Windows, but I make an exception since both are Microsoft...360 was built to share games with Windows as far as I understand.
Here is a list of exclusive no old IP's from previous generation, no ports, high scoring games...
Its another story if I counted older IPs like GT5, Tekken, Street Fighter 4, CoD, KillZone, RE5, Banjo Kazooie, Fable...etc
