I'm sorry but I can't see that Warcraft Strategy would reach its birth.
AOF seemed as a better "warcraft version" of AOS and it is about to swallow the entire Warcraft Strategy.
Before that happens, I would suggest to merge the Warcraft strategy to AOF since the races, units and story are really similar (So we can increase development rate).
BTW Game of Thrones Strategy is a good suggest but not all are fond of it or they know less about it so that won't work as well.
Yeah and about the factions, I have seen some of those.
Factions are larger and more diverse than Races. Most RPGs on PCs fail to make it
Faction-Based. I think it is not time for Faction-Based RPGs and maybe we are old when they come out (If they will).
