I think a building minigame is something that the bedrock edition Cubecraft server is lacking. I think a game similar to build battle would work great on Cubecraft. While games similar to build battle are on other bedrock servers, I don't think that is a problem since they are some other Cubecraft mini-games that are also on other servers. I think Cubecraft could make a great build battle style mini-game that would be unique enough and very good quality (just like the other Cubecraft minigames) to differentiate it from other servers versions.
