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.
