I was going to wait and buy the PC version when it came out. I ended up buy the X-Box version because I just couldn't wait. And it's a great game, all the improvements are just that, improvements. I love all the changes. The ending is a little weak, but I can live with that. But there are other issues, dialog trees that get screwed up, random freezes and slow downs (not just framerate either), a multitude of other nuisance bugs that on their own are not bad, but when all combined, get on your nerves. The more I play the game, the more I appreciate the game mechanics, and the more annoyed I get at the random bugs that could have and should have gotten fixed in QA.
It feels like this game was rushed, and I'm not sure who is to blame, LA or Obsidian. I'd like to be able to blame LA, and hope that Obsidian was pressured into releasing the game early. I haven't seen any posts on here from Devs or Admins, acknowledging any of the issues many are having, which makes me worry. On that note, I might have to borrow the PC version from a friend, to find out if it's worth buying. Because a PC version of the game I got for the XBox is not worth it.
