I've decided to just get it on the Xbox (hopefully it works. It should, though).I think that's the (big) issue at this moment. I've already seen too many comments from people not knowing what their specs are. And bought JWE2 because they were able to play JWE (or PZ).
I think if you have clean/well organized pc and don't match 1 minimal requirement, there's a chance you'll be able to run the game (maybe more crashes and bugs)
But it's a gamble. People could buy it, try the game and refund the game within 2 playing hours if it doesn't work.
I may try to update the graphics card anyway, to play my current games on higher graphics.
Goodbye, JWE 2 PC. Hello, JWE 2 Xbox
