What PC games deliver deep simulation, strategy, and enduring communities?

[AlexanderT]

I've just built a powerful new gaming PC after years on consoles, and while I'm excited to dive into the platform's strengths, I'm feeling a bit overwhelmed by the sheer library and unsure where to start beyond the obvious AAA titles. I'm particularly interested in games that truly leverage PC hardware with deep simulation, complex strategy, or immersive modding communities that extend their lifespan for years. For seasoned PC gamers, what are your personal recommendations for must-play titles that define the platform's unique advantages, especially those with enduring communities or gameplay depth that you keep returning to long after release?

Nice rig. If you want depth and longevity, start with Crusader Kings III, RimWorld, Factorio, and Cities: Skylines—the mod ecosystems there alone will keep you busy for years.

For a broader PC-dedicated go-to list, you can’t skip the grand-strategy and empire-builders: Crusader Kings III, Victoria 3, EU4, and Stellaris all have huge mod scenes and ongoing content. If you like systems-heavy play, Factorio and RimWorld scratch that engineering/curation itch, and Minecraft remains a perpetual modding hub.

I cycle between CK3 for dynastic politics, RimWorld for emergent storytelling, and Factorio for logistics puzzles. The common thread is strong mod support and a healthy dev cadence. If you’re easing in, curate a small mod list—quality of life tweaks, a few balance changes—and build a routine around learning one game at a time.

Don’t overlook Minecraft. Its mod scene alone can carry you for years, from automation packs to huge survival worlds. It’s a different rhythm than the big strategy games, but it’s PC-commanded longevity.

What mix of vibes are you after—grand strategy, management/simulation, or open-world sandbox? Any preference for single-player vs. multiplayer, and do you want cross-platform titles or native PC exclusives? I can tailor a starter shortlist.

Starter shortlist: Crusader Kings III, Stellaris, Europa Universalis IV or Victoria III (your pick), RimWorld, Factorio, Cities: Skylines, Minecraft. If you want a space-sims edge, Starsector or Distant Worlds can scratch that niche too.
