I haven't played Factorio (yet...), but the trackpads work surprisingly well for other mouse based games such as Planet Coaster, FTL, point and click games etc.

I haven't played Factorio (yet...), but the trackpads work surprisingly well for other mouse based games such as Planet Coaster, FTL, point and click games etc. While I wouldn't play RTS games on it, the pads combined with the fantastic steam input that lets you rebind any button to any keypress (or a macro of presses) makes it so you can be fairly sure you can play most mouse keyboard+mouse games on it.
