For pirating fitgirl, gog-games, and csrinru have always worked and been safe for me.

Grim Dawn is an arpg that can be taken pretty slowly. It's a spiritual successor to Titan Quest but it's similar enough to Diablo 2.

Project Zomboid is a very good isometric zombie survival game. You can change sandbox settings to make it as relaxed as you want. You can also focus on farming, reading, or something instead of fighting zombies.

Kenshi is a unique squad-based post apocalyptic rpg. The combat is essentially mmo combat and you can do whatever you want in it.

Mount and Blade Warband and Bannerlord are very good. Warband is older and dated now but will still be fun if you haven't tried Bannerlord yet. Bannerlord just has a lot of improvements though.

Divinity Original Sin 2 is a really good dnd game. It's turn based combat and can be pretty easy with lonewolf and physical damage.

Baldur's Gate 3 isn't fully released yet but it's made by the same people who made dos2. It's also a dnd game but in a different setting with different rules.

Kingdom Come is an ok rpg. The combat gives you the illusion of being challenging and skill based but in reality it's just almost entirely dependent on your stats. You can just use headcracker and grapple and be fine.

I bought Partisans 1941 but haven't played it yet. It looks good though, you fight nazis behind enemy lines by finding friends and scavenging I think.

Minecraft is also a game. Make sure to get fabric and sodium though. There's also Minetest which I haven't played but have heard good things about.

Gta 4 is a good game that still holds up. Gta 3 and Vice City are good but dated, don't get the released versions they are just downgrades.

Alice Madness returns looks good but it needs a laundry list of fixes to play, like some important keybinds can only be set in the config file. I always wanted to play it but it's such a bad port that I never bothered.

Splinter Cell chaos theory is good but also needs a few fixes I think.

Age of Wonders 3 is a good but hard game. I dont remember what genre it is, it's like an rts with turn based combat.
