Becuase I just walked for like maybe 1-2 hours max and I found a wall. I recall last time I played - I set up my base at the edge of the map (unknowingly) and that made me quit - because it really limited my exploration
The map is also <filled> with towns and claims - making it really really hard for me to actually find a good spot to set up without the danger of maybe getting wiped out the next day.
Is it just me or is this map really just too small?
