Please no. Someone tell me it's just an unconfirmed rumor. Why would they do such a thing? I am at very high risk for Factorio addiction, and the only reason I haven't played it yet is because I don't play PC games anymore. But I do have a Switch, and having Civ VI on there was enough of a problem, thank you very much. Goodbye everyone!
May I also suggested City Skylines on the switch? It has a great addiction management feature called high RAM usage, so when your city reaches 200k citizens the game will force close repeatedly on you.
Personally I'll always prefer mouse+keyboard, but it's also fun to play games in the living room.
