Multiplayer Games Recommendations

I was shocked when I searched this on the verge and found NOTHING! So my question is: what are your favorite local multiplayer games of this gen? Ex: Super Smash Bros, Halo, Borderlands... anything split screen, NOT 1 local, i.e. AC. I need a game where skill is optional, as me and my little brother are opposites. (I prefer stealth since I suck at dodge/cover, he prefers guns blazing...) We have all three game consoles... we already have:

Mario Kart

Super Smash

LBP2

Borderlands

Halo ODST

CoD: MW2

L4D2

Rockband

Mario Strikers Charged

Kirby's Epic Yarn

Portal 2

Warhawk

Modnation Racers

We don't really prefer any genre, but XBox/PS3 is preferred. Thanks!
