I absolutely love Kenshi. But once I built a fortress in that green fertile valley near the terrifying religious dudes and got strong enough to kick their ass whenever they came knocking, I felt like I had kind of "won." I made a functioning society that wouldn't completely suck to live in. At that point I started sending my main character out with a few close companions to do adventurer shit, but it was, funnily enough, too easy at that point to be very worthwhile.
