Xbox 360. Direct save imports is important to me and I don't believe for one second that The Keep will be anywhere near as good as Bioware keeps claiming. What little info there is makes me think it just isn't up to snuff.
Even if my computer could play it (and it can't) I wouldn't feel as secure on a PC as I do with a console. I've had far too many issues regarding the PC. I use them for typical spreadsheets, essays and internet. For gaming? Hell no. Tried a couple of times and regretted it when the PC and laptops cr*pped out. All those saves, all that work, all for nothing. My backup data on external sources always had some of the stuff corrupted due to 'reason's completely unknown to me.
But when I say I trust consoles, I am not referring to the new generation.
