You know I understand your worry. We all want dishonored to be wildly successful and fulfill every promise that its developers have given us. And truthfully I think it's going to deliver. I've watched interview after interview, demo after demo, gameplay footage, read pages, clicked links, literally researched as much as I could to make sure I wouldn't be let down. After all the content I've read/ watched I know dishonored will be exactly what we had all hope for. If not better. 10 years from now, people will be posting on a forum, somewhere, with a title reading "most revolutionary game of all time?" And the majority of the replys will say "dishonored". Boom. That just happened.
I agree. I have also done enough research without spoiling myself. Everything I've seen and, more importantly, heard, is that this game is polished to the core.
