Hmmm. What resources would they use, minerals or gold? Vespene or lumber?
I kind think that might work if they SC gameplay was repurposed for new WC races. Something like Naga, Legion and Silithid/Old God armies based on Protoss, Terran and Zerg.
Or vice versa, and give Starcraft the 40K treatment. Undead to Hybrids, Orcs to the Chaos Space Orc easter egg in WC3, Night Elves into Xel’Naga and Humans could be UED.
