I think most console users haven't expericened Witcher 1 and 2 ,especially Witcher 1. And most of them are expecting!So , do it ! CD Projekt!
there is 2 problem:
1. this game mean to be played with a mouse and keyboard. console force you to play with a controller (gamepad) so you cannot play it well.
2. this game is really old. it use Aurora game engine, that cannot be ported well outside windows (they made a eON port for mac and a wine wrapper for linux).
Also, despite having good graphics, it does not require a powerful computer... it's old so you can play it in virtually any computer.
it is a really nice game, I like it sincerely more than the witcher 2. it is the fact that they have made a port for console that made the witcher 2 worst (the controls were difficult with mouse and keyboard, the gameplay totally different (much more action, less fun), there were fewer things to do: less monsters, nothing books, no alcohol or food, and story line much shorter).
Anyway, you should play it on any computer you have, it's worth it (just wait until the end of the second section to judge it).
