NDS, check out the stickied topic in Nintendo Gaming Lounge.

that sounds like a matter of opinion to me.We can make but suggestions, it's up to you to decide if they have merit.For the NDS: I suggest Pokemon diamond or pearl, whichever takes your fancy.MMORPG: I suggest E.V.E, but only if your into space ship type games, and who isn't?For the PS3: I suggest Motorsport. I haven't played much of it but what i did play i enjoyed. Watch out for the load times though, there unreasonable.And for the PC: my personal favorite, Baldur's Gate. Good luck finding a copy though. It's a classic.

NDS - Mario Kart DS, or New Super Mario Bros.MMORPG - World of Warcraft, Flyff, or Age of Conan.PS3 - Resistance, or Metal Gear Solid 4.PC - Half-Life, Crysis, or Warcraft 3.

MMORPG, maybe Mu Online?

Since you didn't specify genres and I don't play MMORPGs I don't think I can really help you.
