Apterra is a huge map designed for survival gameplay, or a server, just like a deafult minecraft map. Even though there are much more basic structures in this world, none are made of any precious material imagine a default MC structure a bit more site specific and a little bit better. You can choose your gamemode in-game at start (survival, adventure and creative), and then one of four different starting locations (selecting a location will automaticly set the spawnpoint to that location). selecting "creative" will transport you to the center of the map and set your spawnpoint there. You will find everything you need in the map, there is plenty of stuff everywhere. when in doubt, find a road and follow it.
