I'll always have a soft spot for the Ultima series, ever since Ultima III was one of the first RPGs I played on the Mac in the early 90's, along with Exile 1 and Realmz. I must have been 6 years old and had absolutely no idea how to progress in the game, and couldn't do much about it because we didn't have the internet. Still, the game intrigued me. A few years later I was lucky enough to stumble across the Ultima Collection (Ultimas 1-8), and had to have it. Ultima 7 + Serpent Isle were easily my favorites, despite the automated combat. The worlds were so rich, vibrant and colorful, and there was so much loot that it was a pack rats dream. A while back I wrote a rant on the 'Dex about Ultima 8 and how it was such a bitter disappointment, but I've eased up on the game since then. It's a step down from Ultima 7, but still a decent game in its own right.
A few years afterwards I found out that Ultima IX had been released. Now, this is no doubt where everyone would expect me to say that the game ruined my childhood, but I actually enjoyed the game, in spite of the shitty AI and game-breaking bugs. It was the first 3D RPG I had ever played, especially with complete voice acting. Yeahhh, I know the voice acting is cheesy, but for me it's so bad it's good. And the storyline had a number of plot holes, but I hadn't finished most of the earlier Ultimas, so I didn't know any better. The music was pretty damn good too, and included one of the best renditions of 'Stones' I have heard:

Then there are memorable WTF moments such as when you meet your in-game gay fanboy (complete with a stereotypical gay voice!), a child who throws fireballs at you after you refuse to give him money (despite magic not working), or when you shag a hooker in Buccaneer's Den (complete with a Swedish? accent) and lose karma.
But man, the bugs almost broke me. At one point I saved the game underwater, and every time I tried to resurface the game would crash. It took me weeks to figure out a work-around. Another time a lever for an elevator didn't work in Hyloth, so I had to resort to the noclip cheat. And I broke the game by jumping over the mountains between Britain and Yew, resulting in me triggering the trial for killing the gargoyles before I had even been to Ambrosia. If there were a patch which actually fixed the game-breaking bugs and tweaked the AI, I'd say that Ultima IX would be a decent game in isolation, or 'so bad it's good' at the very least. It's got way more personality than Oblivion.
