I love the setting and the miniatures! Great looking table.
Must say I'm hesitant to get into a new ruleset.
The miniatures can be used in any game...they seem particularly suited for
Stargrave, at the moment.
As for the rules, we've been refining them for three years, and they really are a lot of fun. When John is ready to publish the rules later in 2022, I'm sure he'll record a demonstration video so that you can check them out and see if they strike your fancy.
