Ah, I see part of the issue. OP is a butt for removing the familial link in their title. The BBC headline is more accurate.

Because a) It’s now an international incident, and b) the source is BBC.

All combined? No. Top in playtime by a very large margin over #2? You betcha! 😁

Pulled from my Top Playtime on Steam (so you know you’ll get your money’s worth if you like them!)

• Factorio (Even though the DLC is pricey, it at least doubles the playtime. Though, like RW below, it takes a lot of content/concepts from fan-made mods.)
• RimWorld (Though I dislike how many DLCs they’re pumping out and how much is basically taken from mods.)
• Terraria
• Mount & Blade (Warband 1 & 2 are prime)
• Kerbal Space Program (NOT the sequel)
• TerraTech (The original is a better experience)
• Both the Pathfinder games
• Grim Dawn
• The Riftbreaker
• UnderRail
• Mindustry (Open source/free, but deserves the support from buying it on Steam.)
• No Man’s Sky (They’ve gone above and beyond in shaping up since the clusterf release.)
• The Long Dark
• Rise to Ruins
• Space Pirates and Zombies (1 and 2 are both great, in their own ways.)
• Caves of Qud
• Tales of Maj’Eyal
• STALKER (I’ve heard bad things about #2, but the rest are great, high replayability with Anomaly.)
• Astroneer
• War for the Overworld
• Autonauts (and Autonauts vs Piratebots!)
