So the initial response has overwhelmingly been to keep it as a FiveCore system, just neaten it up a little and integrate it properly.
I will keep it open for comments over the next week or so, though this does make life easier as a lot of that work I have already done, meaning the production time can be far far less.
I didn't want to skew the results by mentioning that.
If this is the path (as it looks now), it won't necesarily be a straight 100% "copy" of the FiveCore skirmish rules, there are some tweaks and adjustments as part of the process, in particular, its likely that a Five Men at Kursk style activation roll will be used.
The content from "Every star an opportunity" will be reviewed for inclusion as well, either way.
