According to steam I have some games with 100 to 120 hours (Dead Cells, XCOM, Rogue Legacy 2 and Hades). I prefer story driven games to be 20-30 hours, but keep replaying short sessions of single-player roguelites.

I think I’ve played more than 120 hours on Magic Arena but don’t have the hours tracked. It’s one of those games that give you incentive for playing every day and grinding a number of wins, and I’ve done that for maybe 3 months, then got tired and dropped it. I like the idea of replaying a game and getting better at it, but not the log in and grind everyday part of online games.

Planescape: Torment is a classic from that era

Streets of Rogue. It’s a top-down roguelike with many different characters and items. You can do the missions in different ways playing solo, but co-op opens even more possibilities.

Suikoden I and II are great PSX RPGs, if you can emulate. Shadowrun (Returns, Dragonfall and Hong Kong) are great and Linux native.
