The 2 best exclusives for ps3/360/wii

[BxN]

PS3: LittleBigPlanet/Metal Gear Solid

360: Gears 2, Ninja Gaiden 2 (personal favorite)

Wii: Mario Galaxy. (I can't name a second one, I haven't played any other Wii game I liked during my very limited playtime with the console, I believe the Zelda game or Smash Bros would get the second spot)
