I want a slow-paced, macro-oriented RTS like Kohan.
I think the Elemental world could really work as an RTS, the units are in place already. It might actually work better that way than as a TBS when I've thought about it. You'd have to strip down some things, but most of what's in the game already would translate.
Kohan is a long-forgotten name except among diehards. Much of that is Timegate was a one-hit wonder, their successor games weren't very popular.
As for Lab Zero, they made Skullgirls. Really artistic game with really friendly staff that suffered more misfortune in one game business than Brad has suffered in his whole career, yet still are surviving.
