I agree that the honesty is much appreciated, especially coming from someone who bought the PC release. That being said Patrick, I really think you should be holding Steam just as accountable as Microsoft or Sony for allowing a totally broken game to be sold on their service. Is there just no QA on the seller's side anymore? It's hard to believe that (as someone who meets all of the recommended system requirements according to Steam and has an Nvidia card) someone could have started up AC:U and played for more than an hour without noticing the huge frame-rate and crashing issues present.
I really hope that in the future console manufacturers and online marketplaces like Steam will have to accept some accountability for these sorts of problems, but somehow I doubt that will take place. I can't complain though, I did get a refund from Steam despite their policies about that.
P.S. You should edit your title duder, it says Ubisof!
Steam/Valve's role is pretty different from Microsoft and Sony. Steam doesn't have a certification process, but Microsoft and Sony do. Certification processes exist to ensure a certain level of quality, but it's a bit more wild west on the PC. The onus is entirely on the publisher on the PC.
