I think if any new structures were to be added into the game, they should blend in with the surroundings, like they are supposed to be there and have been there for some time. This means that they can’t be too exceptional, but they can still be pretty great builds. Also I do think the idea of an award system could have potential. For example, a building can be built in the main spawn area acting as the showcase, there can be awards such as: Most amount of days survived, Biggest building, most creative building, most impressive farm, most wealthy, and so on.
A blocky survival game.
