I enjoy Dungeon Crawl Stone Soup played in the terminal with ASCII graphics. I wonder whether there are other hidden gems out there which don't get attention because they are "ugly"?
I have had some people refuse to even try Baba Is You, because it looks ugly.
I had The Hex a few years even installed, so I have tried it, but only after getting familiar with the style of Daniel Mullins' games with Inscryption I pushed far enough to get interested. Still very clunky, but worth it.
I would say Kenshi with assests that show it was done by one person and a rough UI, also maybe pathologic 2, although for that game I wouldn't say it's the graphics that put people off it's mostly the gameplay, but the geaphics are weird and really grey/depressive
Tales of Maj'eyal. A free to play open source roguelike that I hate. This game is amazing. Fuck this game. Also definitely recommend. But fuck this game. After numerous 10-12 hour long runs, I have yet to win.
West of Loathing and its sequel Shadows of Loathing have a bland grayscale artstyle on the outside but they're absolutely hilarious RPGs that have a lot of heart to them.
Kenshi came to mind as that's a butt ugly game but probably not as "hidden". Graphics look on par with Empire Earth 1 zoomed in but it's really unique and original and the low poly look helps it run on my aging PC so no complaints.
I never got far in it, but I didn't see anyone mention Vampire the Masquerade: Bloodlines. It's fun to explore a world where everyone has noticeable neck seams.
Some people find Slay the Spire's art ugly. Personally I find it creative and original, definitely more personality than if it was just another pixel art game. 😁
Card Quest (Android) has similar dated graphics, but I got kinda into it lately. It's a card-based roguelike, with a fixed deck that only changes with inventory/skill changes.
I remembered thinking teleglitch was absolutely fascinating a while back. Not exactly a pretty game but it's not ugly either, the chromatic aberration effects on collisions is real pretty imo, even if the underlying art is rather spartan
From the games I can recall, Anuto TD (Another Ugly Tower Defense).
I cannot say whether or not it would get attention because of the graphic quality, but I know there are plenty of people who wouldn't play it since it is not 8k super ultra 3D high def masterwork quality graphics and would gladly shit on it because it doesn't have the most realistic graphics out there.
Imbroglio (https://apps.apple.com/us/app/imbroglio/id969264934) is one of my favorite minimal purchase iOS games. I haven’t played it in awhile, but it’s a unique dungeon puzzle game where you place attacks as floor tiles on the board ahead of playing. There’s some consistent rules with ramping challenge, which made it super replayable for me. I loved trying different floor designs, finding strategies, and there’s a small progression system that’s fun. Hasn’t been updated in a few years, but it was a great design despite the rough appearance.
TagPro - minimalist graphics, straightforward gameplay and an insanely high skill ceiling. So good it was banned from AskTheBadWebsite because it was always the top answer for every question regarding good webgames etc.
Stardew Valley, hands down one of the graphically ugliest modern games, like 80's console style. Though it's a really good game and I've put a of lot of hours into it. People say it's meant to look that way as intentional retro styling, but damn it's ugly. I actually added a mod on PC to use AA on the blocky graphics and it makes it look a lot better.
