Board Game Arena

I have seen it too, especially in tournament play. Perhaps keeps as-is for real-time games, allow optional visible/hidden moves until all commit in turn-based games, and make tournament/arena play mandatory hidden moves until all players commit?

Most structures score zero points at the end of the game. If the structure does provide end-game points then the process is described on the tile or player-board itself. (Mouse-overs are helpful on BGA).
