So I played an hour of Ultima Underworld. I fiddled with it a bit last year, so I just restored the game I was playing back then where I had explored only the first few rooms. First off, the game handles fine when it comes to turning and moving back and forth, but fighting seems awkward, as the three different strikes all have a charging gauge and the actual swings move across the screen a tad slow. However, monster attacks are also slowed so it balances out and gives you a moment to actually think before you attack. Also, jumping is difficult for me to time properly, but hopefully I won't need it much.
The atmosphere is great, where the dungeon is appropriately dark and encourages you to use light sources. The remains of past people that litter the floor is also a nice touch, as well as a love letter that I found on one of the condemned. I died a lot, mostly because of slow acting poison. I also found some leeches down a river, and I think I remember my friend playing this game and using them. They remove poison, but cause damage if I remember right, so even if you find a bunch of leeches you want to avoid even minor poison. I like this dynamic.
I found some runes, but I haven't taken the time to learn how to use them yet. Weapons and armor decay in quality during use, which is also a neat effect. I found a friendly human, but not the village of whence he comes. I did find some lone, not so friendly goblins, but after killing them I tried talking to a goblin behind a portcullis and he actually invited me in to meet his king. Before this I also stumbled into a stressed rat that didn't attack me, so I refrained from slaying it. I appreciate the idea that I don't have to kill everything I meet down here. It makes me feel like I am playing the Avatar again, and not just some genocidal maniac who slays anything that doesn't look like him. I'm getting into this and it brings back warm memories. Somehow it feels like Ultima despite being from a completely different playing perspective.
