My worst experience was Fallout 2. I could forgive bugs in such a complex game, but I can't forgive the sheer amount of terminal bugs. I played half way through the game and ended up with a save game that had a bug which wouldn't let me go any farther.

In a rage I pulled it from my computer and left it. I went back to it few years later and got the final patch for it. Still some minor bugs, but a much more enjoyable experience.

One of the reasons I rarely buy games when they first hit the shelves. A) Price, B) Bugs, and C) Later Versions usually come with more extras, i.e. Gold Versions.
