So after much back and forth in my own head, I decided to pick this game up for myself. Personally, I loved Fallout 3, though the story lacked in terms of... well, everything, it was still an epic adventure and home to a plethora of interesting features.
So, after purchasing the game, I race home and start my studying for an Earth Science test... Damn, university sucks :x
After I finished, I installed the game to my 360 and started it up. What I was met with -- for the first 5 or so hours -- was me pouring my heart and soul into this game. The beginning of the story drew me in, the characters in the first town were interesting and felt relatively fleshed out. Alas, things could not remain perfect forever, and it's where I ran into my first bug. The freezing issue was horrendous, and it was a gamebreaker. Frustration set in, and I turned off my 360 and walked away for a while. The nagging set in and I decided to come back, and after uninstalling and reinstalling the issue persisted. So I turned off the auto-save, and lo and behold, the freezing issue has yet to return.
Thankfully, past the bugs is a fantastically engaging game that really draws you into the fold. The world is beautiful (as far as post-apocalyptic worlds go), and the gameplay/factions/missions remain thoroughly interesting.
After this, my advice to you Obsidian is this. Stick to what makes you good, and that is engaging stories, and when you've done that, please, for the love of God, test your damn game.
