You could use system requirements lab website to see what games you can play with your specific computer. Instead of knowing what games you want to play but don’t know if they will work you will instead have a list of games you know will likely work and can pick from those.

Minetest is a decent MC clone, open source and whatnot. There’s also a few mods out there that tries to replicate it. (inb4 someone says minetest is an engine and not a game)

Roguelikes:

• Dungeon Crawl: Stone Soup (http://crawl.akrasiac.org:8080/)
• DRL (https://drl.chaosforge.org/)

I hate Epic launcher but if you can get weekly free games from epic store.

Guild Wars 2, has free to play tier, and no monthly sub if you buy. Definitely a dank game and I ran it for years and years on a piece of SHIT laptop from 2013-2014

Someone else said Vampire Survivors, the game I like a lot recently is 20 Minutes Until Dawn. Lots of guns, upgrades, and characters to have fun with.

Great roguelike “Shattered Pixel Dungeon”

This is a free (as in freedom) game, I’ve done dozens of runs, there was enough depth and graphics are pixel art. Available for computers, phones, whatever

I also have this problem so I’ll suggest some games I like to play. They’re not free unless you’re up for piracy.

Disco elysium (visual novel esque, unique and interesting, multiple choices, indie) - incredibly well written game with lots of dialogue and heavy political themes

Morrowind (open world, RPG, multiple choices, retro I guess) - oldest elder Scrolls game but maybe the best in terms of lore and freedom in game mechanics

Oblivion - same as morrowind but imo not as good

Factorio (indie) - if you like this kind of game you’ll never need another game suggestion because you’ll be too busy playing fsctorio

Rimworld (indie) - as addictive as factorio

Oldschool Runescape

Have you tried interactive fiction (text adventures)?

There’s a yearly competition (https://ifcomp.org), the winners of the last 27 years should keep you busy for a while. They come in various file formats you will need players for, but some have a “play online” function.

Highly suggest SIGNALIS

It follows the style of slient Hill and the original resident evil 1 and 2 with its own unique storyline if you are into survival horror

Bit of a different genre, but I’ll throw HoloCure in here.

I would suggest giving a look at Crosscode, Katana Zero and Hotline Miami 1 and 2. They are some of my favorite games. Katana Zero and the Hotline Miamis are shorter, story focused games, while crosscode is longer, with side quests and puzzles.

Stardew Valley is a great farming game with RPG implementations.

Team Fortress 2 is a good choice. I used to play it when I was getting into PC gaming but still only had integrated graphics. I recently got back into it, since it’s pretty much the only FPS I really enjoy. The game hasn’t had updates in a while, but it still has a dedicated player base.
