For me difference is that Factorio is not containing any way to spend money in game or spend to avoid grinding. While typical mobile money has grinding solely to force you to pay. Note: in Factorio my typical strategy is to use mod that makes me start with construction robots, to skip any kind of drudgery at start. Modding API allowing it is deliberately open and explicitly created to allow this. In typical mobile game I would need to pay large amount of money for that.
