I never played Mine craft, which i hear this compared to. So, my question is, are they really telling the truth when they say if you can dream it you can build it. Can you change everything? Including the combat system, Npcs, ect... Or is this just like a place to make sand castles. Could I make a race track, with a bunch of hard turns and loops ect. Like Interstate 82 for battlefield 1942? If stuff like that is possible I am getting the TrailBlazer.
