It's legitimately insane how many seemingly unrelated videogames can be directly traced back to Underworld in some form or another. Like, to get the obvious out of the way first, it established the DNA of the immersive sim genre, so if you like games like System Shock, Thief, Deus Ex, Bioshock, Dishonored, Prey, all of those games were either made by people who worked on Ultima Underworld (sometimes by the same studio even), or otherwise directly influenced by games that were.

But also, if you like any first person shooters influenced by Doom and other ID Software games? John Carmack was there when the demo of Underworld was first shown and decided he could create a faster texture-mapped first-person 3D engine. Which he did, at the cost of sacrificing true polygonal 3D environments in favor of the pseudo-3D that he would use for Catacombs 3D and Wolfenstein 3D, eventually resulting in the creation of Doom. RPGs like the Elder Scrolls or Gothic? It would take all day to list off how much they directly owe to Ultima Underworld. That videogame trope of finding out what happened to the occupants of a place through finding in-game logs and documents? It was established by Ultima Underworld and popularized by one of its successors.

That's without mentioning how many games directly cite it as an influence. Some already mentioned like Bioshock, Deus Ex, and Elder Scrolls, but also like. Half-life 2? Tomb Raider? Gears of War? Vampire the Masquerade: Bloodlines? All cite it as a direct influence in their game design.

Only in the arena of Ultima II can you travel throughout the solar system, explore deep dark deadly dungeons, dine at your favorite restaurant, meet prominent people within the computer industry, and be seduced in a bar.
