For me it has to be Toki. The characters were so weird and creepy, especially the bosses!
Probably Morrowind. The game is ugly and the mechanics are a bit clumsy, but damn did I love it. Prolly clocked over 3,000 hours in Vvardenfell man.
I love Morrowind so much that I refuse to admit to its ugliness. I will choose to believe that the less-than-perfect graphics simply enhance the alien look and feel.
Same with the fog to cover up draw distance issues.
“It’s called an art direction sweetie, look it up.” But without any sarcasm.
Kenshi. It’s simultaneously janky and beautiful.
Pathologic is a pretty ugly game, but, if anything, it adds to the charm and atmosphere of the game.
For me, it has to be Dragon Age Origins. I love the brains out of it, but it is as ugly as you can get. Thankfully the rest of the game is fantastic.
