I'm really curious how the bug situation will be with this release. Black Flag was pretty decent on next-gen, but that one had the benefit of the previous gen versions having been out for a year already. This is a completely fresh release, a la AC3!
I've recommended several people to get this game somewhere in February, when hopefully most bugs will be ironed out, but who knows it will be fine.
I worked really hard in getting issue tracking in this weekend along with the feature tracking into
www.techingames.net before the next Assassin's Creed release ... I still need to pretty it up (as I need to do various other bits), but I managed it and its live. Hope it is of benefit to someone. I'll get Unity myself, so I'll do my best.
