I've just played through the demo and my opinion...
The game is good, quite fun really. Simple concepts lead to a game of complex strategy much like classics Chess and Go; Bronze is essentially a board game style game played on the computer with the aim to have as many of the boards squares (actually rectangles but it sounds too goofy to say "rectangles", forgive me purists
) in your control at the end, or to deny your opponent any moves.
Ownership of squares is obtained by building in a square, some buildings take silver, some give silver and some cost nothing. Buildings can have other abilities, like flipping ownership of opposition adjacent tiles or protecting your own buildings from flipping. Squares represent terrain and different terrain has different effects, or only allows certain buildings to be built on it.
Download the demo and give it a go.
