daggerfall-unity VS UltimaHacks

You can get it from Daggerfall Unity's official website, dfworkshop.net. There should be a link to the download page at the top.

If you're trying to install DFU, go to their latest release, download the mac version, and do not use the GOG cut, it is apparently incredibly bugged, messes with a lot of mods, and using either the bethesda website's download or the steam version for the original game files (both are free) skirts around some bug that comes with the GOG cut. I don't know what the GOG cut even is, but I've seen almost every mod on the Nexus say it's bugged and to not use it, so idk. If you don't care about mods, you will. Daggerfall is a Bethesda game, so you're bound to mod it to hell and back.

Yes! Here's their website

Alternatively, check out Daggerfall Unity.

My favorite way to play is with https://github.com/JohnGlassmyer/UltimaHacks

There's the GOG Version with Ultima Hacks. Has a lot of quality of life improvements.

GOG is fine, I've got several games with them, no problems. Also, check John Glassmyer's Ultima Patcher, he has patched mouselook for UW1, and it works very well. Here's a link explaining what the patcher does.

And luckily, someone created a mouselook mod for them recently that works very similarly to System Shock Enhanced Edition. It also lets you interact with objects using the E key rather than choosing "open/use" every time, which is huge as well. You can get it here: https://github.com/JohnGlassmyer/UltimaHacks

Wow that really sucks. Ultima Underworld is an incredible game that 100% holds up today with the only exception being the controls, which thankfully someone has mostly fixed by adding a mouselook toggle and WASD controls: https://github.com/JohnGlassmyer/UltimaHacks (there is also a Unity port, but it has some pretty major bugs/missing features still).
