Give me one or two games for PS3 or 360 that you think would  particularly interest a Nintendo fanboy and why.

Not that I'm really looking hard into picking up a new system, but we've built up a lot of stigma as to what types of games are on what console (360 is all shooters, PS3 is all RPG's and God of War, Nintendo is all waggle and kiddie, etc.) that I thought it would be fun to look at some games that break those molds and might make a Nintendo fan look twice.

Edit: To clarify, I'm not just looking for  "what games do you like for your system?" but what games for the HD twins do you think would really intrigue and entice your typical Nintendo fan particularly?

What type of game are you looking for?

Assassins Creed - Free roaming with Metroid style enhancements.

Batman: Arkham Asylum - Another free roaming game with Metroid style progression based on enhancements.  And its Batman...with the original writers and cast from the Animated TV series.  that should be reason enough to buy it.

Marvel Vs. Capcom 3 is a lot like Tatsunoko Vs. Capcom...

Like I said, I'm not looking for anything in particular, just playing a little game based of what you think a typical "NINTENDO FAN" is interested in.

360 is all shooters, but go for them.

I'll recomend Mushihimesama Futari 1.5, Espgaluda II, Muchi Muchi Pork/Pink Sweets, Bullet Soul (they're region free, you can import and play), Deathsmiles, Guwange on XBLA, also on XBLA, Ikaruga, Strania, Triggerheart Exelica, King of Fighters Sky Stage, Detana! Twinbee(no, you have this on Wii).

Hey, i'm a typical Nintendo fan, so i know what i'm talking about. :p (j/k)

Try

Bioshock 1 or 2 (First Person Shooter/Adventure)

Infamous (Action Adventure)

Ratchet & Clank TOD or ACIT (Platformer and Shooter)

Little Big Planet 1 or 2 (Platformer)

Mass Effect 2 (RPG)

Nier (RPG)

Uncharted 1 & 2 (3rd Person Shooter)

Valkyria Chronicles (Strategy)

God of War Collection or 3 (Action Adventure)

Most of the game have demos on the Playstation Store.

uhm what ?

Pretty sure 360 still has the lead over the PS3 in RPGs. Localized ones at least.

Too Human, Mass Effect, Risen, Tales of Vesperia, Blue Dragon, Lost Odyssey, Divinity 2, MagnaCarta 2, Fable 2, Fable 3, Infinite Undiscovery, Torchlight, The Last Remnant

PS3 has more action-adventure games or hack'n'slash which probably fall under the same category and platformers (though both consoles don't have that many).

This is the kinda responce I was looking for. Games for other systems that you can equate to the traditional nintendo catalouge.

Assassins Creed has always looked intersting to me. Good choice.

I think that a "Typical Nintendo Fan" is way too general
