I'm finding this incredibly frustrating, having preordered it through Steam and I still can't get it to even start up, let alone deal with the bugs. I preordered largely because I'd seen a talk from last summer by Chris Avellone on the dialogue and storytelling system the game uses (which even the most damning reviews seem to say is pretty stellar), and honestly I'd even have been happy with something that was a flawed gem, much like how KotOR2 was. However, a game that I can't even get to start is pretty ridiculous -- I don't think I have had this problem with anything I bought through Steam ever, and so far nothing that's been suggested by technical support has worked to fix it. :/
To be fair, I suspect my issue is actually something with the DRM, since I don't even get the prompt to enter my activation code when I try to launch it, but that doesn't really make it any better. I've had really high hopes for Obsidian, just from their pedigree: KotOR2 really was excellent until the rushed-out last act, and I actually applied for a job there years ago and got some of the most thoughtful feedback I've ever gotten on a practical test. Unfortunately, my experience with Alpha Protocol has made me reconsider preordering New Vegas, which should be a sure bet. I'm sure I'll end up getting it (and I suspect a game built from an existing engine should be a bit more robust), but I'll probably wait for the reviews before picking it up.
