They're half-ass ARPGs sorta mixed with half-assed RTS games. And generally pretty fun overall. I've played and beaten 1/2, the mediocre RTS elements are there basically to give you a feeling of having an army at your back while you go around doing heroic shit with your main guy/s.
I'll wait till this drops in a price a bit; while it is on my steam wishlist, I also have a dozen or so games I need to play still before I spend any more money~
