Dominion Chess

[Xavier]

If I had any spare time I'd love to develop it with you ;-)

I think you'd have to keep it to just 2 equivalent nations, or else it would rapidly stop being anything chess-like and would just become simplified dominions. Although, you could have every nation have a single, (balanced!) special ability. Ermor gets a free pawn every couple turns, marignon spreads dominion faster, Vanheim moves faster (to simulate their sailing), abysia can sacrifice pawns to summon knights.

You could also have minor special abilities for kings, to simulate choosing different pretenders.

If someone could come up with a way to implement it Online (something web-based), I'd be into spending some time hammering out a balanced and fun rule system.
