This is probably the best light war/board game on Steam. The idea is that as you capture parts of the board, you slowly remove them from the game over each turn and convert them into resources. The idea is to be the last player standing.

You can accomplish this by either taking over their bases, or destroying the land they stand on. But be careful, because in destroying them, you also risk destroying your own ground as well.

Games quickly become a scramble of resource management, and fighting against the clock.
