Factorio killed just about all ability for me to actually do normal work for two weeks. It took over my brain: all thoughts were about logistics, supply chains, the structures that would deliver them...
It was highly addictive, and fun and fun at first, but then got stressful. I've never been so relieved to finish a game, or had such an anti-climax watching the simple rocket animation.
I can't say I hate I hate the game, but saying I like it doesn't quite feel right either.
