There is nothing out there that gives you more freedom than the grandfather colony game. Dwarf Fortress is getting a remake with some graphic revamp also.

Quake is a classic and it is a happy place for many hardcore gamers. Skill without ♥♥♥♥♥♥♥♥. If you are an old man you probably have 1000h+ in Quake multiplayer already.

Didn't age the best, but it's still the only game that can offer that nomad adventure experience, and you can easily sink a thousand hours into it. The freedom in Kenshi is exhilarating.

A distillation of the survival genre. Don't let the graphics fool you, as the depth this game has is astounding, and it is getting deeper with updates. One of the best zombie and survival games.

If you love tactical games and hard games in general, battle brothers will have you spending a thousand mercenary men to the harsh reality of the lands. Pure tactics. Great replay value.

Runescape is more of a nostalgia trip for many, but it holds up today as a game with ridiculous amounts of content. If you like grinding numbers, and leveling up, getting rich, this is it.

Souls-like games are games that don't spoon feed you and expect you to better yourself along the way. If you have a decent machine, Elden Ring is a good intro to the Souls series.

With a great modding scene to lift this game to modern times, you will have a lot to chew through in this OG post-apocalyptic setting. A ton to discover and explore.

If you are a rhythm game person, this is the best one on steam. Only for those rhythm fanatics. You probably already got into other rhythm games like osu! and some classics. Hit the keys, to the beat.

An absolute classic. This game can offer endless tactical and fantasy strategy gameplay. Also check out mods (like WoG). Probably the best game of its genre. 2,000h+ game
