Hmm, the only one ive played in the last 4/6 months or so was one I did for the Nearly Immortal acheivement, and I really liked it. Called "North". I found a log cabin in a snow area next to grasslands on all fronts that had a forge in it, a nice city NE, a town NW, a trader North that had a workbench, a few ammo crates, and a forge and a trader a few mins south that had a forge, workbench and a chem station. I had everything I needed to survive the 1,250 minutes or whatever without even needing to visit the city but once.
I didn't find a prison but, like I said, I had everything I needed lol. To add to its awesome, the trader North had a little tiny tunnel RIGHT outside that lead to a nitrate and iron mine. Spent 15 mins and got a handful of stacks of nitrate and iron... I was living nice.
