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.

I personally am not interested in this unity remake because I think it's kind of visually ugly (the modernized UI font and new 3D models clash with the original visuals in a pretty awkward way that loses a lot of the original's charm)

But it's still a remarkable effort, and for anyone who sttruggles with the original's controls it might not be a bad way to experience an extremely influential game that still holds up as one of the best dungeon crawlers of all time.

You gotta play dolls with your characters.

Slap them in AUs, make silly fanfiction, make "what if?" senarios. You gotta recreate the feeling of taking your toys out as a kid and improv-ing a story on the spot. You'll get a sense of what makes them who they are outside of their main storyline.

Take a piece of yourself, expand and explore upon it. Create characters and storylines that are love letters to those you've cared most about. Take that little ball of hate and/or despair and give yourself a little therapy lesson.
