hmm i dont agree with any of the above, i think something that makes you feel like you can roam free yet always points you in the right direction (think FF7) yet has to have a not to complicated level up system (i recently picked up NWN2 and the level up system has far too much in it for my tastes, i dont want to read 30 different abilities for each char before deciding what to level) i dont like MMORPGS so i guess i want
wide open spaces to explore, with a clear direction of where i should go, with fairly limited char level system(give me points to place but keep it simple like the one in Diablo2), i prefer a third person view point with direct control of the character using wasd keys, and a turn based fight system implemented like the one in FF12. And of course im not bothered about PC or Console if its a good game.
