(This is the same guy behind Warplan: Pacific, by the way. So he has a pretty solid rep already.)
This one is high up on my wishlist. It's essentially a low-fantasy, grand-strategy wargame of moderate complexity. It's been compared to Shadow Empire, albeit much less daunting (and of course it's a fantasy, not sci-fi, setting). Curious if anyone else has checked it out (there is a demo available).

In addition, the developer is currently working on adding a random map generator (he's calling it the "Warlords" scenario), which should greatly increase the game's replayability.
