A lonely Redditor asked for solo game recommendations and the community delivered pure digital crack. Here are the best PC/Switch games to grind for hours.

Debugging a spaghetti codebase at 2 AM, I took a mental break on Reddit and stumbled upon a tragically relatable post: "I don’t have friends to play online, need something that’s satisfying alone... love games where I can grind, explore, or unlock things. PC/Switch."
Felt that in my soul. In an era where every major publisher wants to force us into live-service co-op, sweaty PVP arenas, and toxic voice chats, this loner's plea actually spawned a god-tier list of time-sink games. If you're a dev or gamer who just wants to avoid human interaction after endless Zoom meetings, bookmark this list.
OP is looking for the holy trinity of single-player mechanics: grinding, exploring, and unlocking over dozens of hours without getting bored.
Honestly, skipping the toxic PVP lobbies and avoiding those predatory P2W gacha traps is a massive W. Sometimes, you just want a pure progression loop. No whales crushing you with their credit cards, no squeakers flaming you for a missed skillshot. Just you and a well-crafted digital world.
Diving into the comments, the recommendations fell into a few distinct playstyles:
1. The Sandbox & Survival Tryhards:
2. The F2P Loot Farms & Cozy Vibes:
3. The Cinematic Masterpieces:
If you're an indie dev taking notes, the secret sauce here isn't forcing multiplayer or aggressive monetization. It's the progression loop.
Games like Satisfactory and Subnautica nail the dopamine hit of unlocking the next tier of tech. Give players a meaningful grind, a world worth exploring, and respect their time. Build a solid foundation without massive FPS drops or buggy launches. Do that, and they'll happily sink 200 hours into your world, totally solo.
What's your go-to solo grind game when the codebase is driving you insane? Drop it in the comments!
