I heard from my cousin that if Awakening didn't do as well as it did, then it was going to be the last in the series...
I would disagree...
Medipack would be more for something like healing a unit...
and bullet-proof vest could be like sacred water (or whatever it's called) where it increases your resistance (except for defense this time), but then each turn it decreases...
and instead of steroids (if you want this to be child friendly) then do something like Protein (Pokemon anyone?) or weights...
it also depends on whether or not you want to be futuristic or not. If you do, you could do something like "titanium lacing" (for the skeleton). In this case, you could do a BUNCH of stuff, I think...
Also, if there's no magic, then wouldn't resistance be pointless?
After many edits, only then do I realize that you guys already have stuff figured out...
