It's really nice, yeah, but tbh it's not too impressive
Flatgrass may be made for building, but it scales down the coolness factor of anything built by about 50%
It's made for flatgrass. It's a survival map. You have to hold down the outpost while creating a self-sustaining environment in order to survive.
You have to
*Create a cobblestone generator
*Get a farm up and running
*Terraform the surroundings
*Survive the endless waves of slimes, and the harsh nights.
*Eventually find a temple and repair a nether portal, then you go from there.
