For DF, the classic version does have some mouse controls with DF hack. Just download the Lazy Noob Starter Pack (I think that’s the name) and you’ll be started in less than 10m with a character pack and plug-ins.

Yes, I’ve played Aurora4x. It’s a wild game. I think the worst thing isn’t just that it looks like a spreadsheet, it’s that it is just spreadsheets with a game using it as inputs. It also doesn’t tell you anything about how things function or what to do to get anything done. It’s similar to DF in some of those ways, except DF you can still play some without fully understanding it. A4X really requires a pretty good grasp of most components of the game before you can even start.
