I liked Ultima 7, but didn't actually do any of the missions or follow the storyline. It was the first "big open world" for us, so we just went around slaughtering, stealing, and putting things in weird places and laughing about it
The only thing I can really remember though is a giant pile of naked dead people we put right beside the road just outside of one of the towns, and right beside it was a giant pile of clothes
I have looked at a bunch of the different Ultima games and I did play Ultima 4 or 5 for a while, and that time followed the story. But did not finish. Also Ultima 8, but just a bit.
Other than that I've played Skyrim but the stupid inventory system and me accepting all the quests and not playing frequently enough just got too confusing and annoying.
I really like dungeon crawling games. I used to play a text based one for hours every day, just ASCII dungeons, and you walk around, collect stuff, fight monsters, and collect treasure. I can't remember the name though.
I also quite liked Legend of Grimrock. It's the same thing as the ASCII game except there's pretty graphics. Some people will find it limiting because you can basically only look in 4 directions, like in the ASCII versions. I almost beat it too, but eventually the levels just got too elaborate, and it was all a bunch of the same concepts, just piled on top of each other, plus I dropped some item I needed and would have ot look for it 3 levels ago so screw that, I uninstalled the game, that was as much entertainment as I was going to squeeze out of it. Which was a lot, and I only paid $5, so money well spent
