Using miniatures across game systems is potentially smart busines. I would have never in my life considered age of Sigmar but now I have shadespire figures and will eventually have some rat guys and may actually buy into a Skaven army if it suits me.
same thing with warmachine and company of iron. I almost bought back into warmacine thanks to CoI existing. I didn’t given I need more minis like I need a hole in my head but overall yeah when companies put more potential uses into a miniature I’m way more likely to buy it and invest the time in painting it.
Time is the primary resource these games compeat for.
With the descent app I think FFG should consider putting some of the Rune Wars figures into descent and I think there is no real reason Star Wars could not also follow suit.
