Hello! May I offer you tushanshu? We're a slow game (though hoping to get to medium!) and very backtag friendly. No power nerfing, and there are occasional horror elements to some of the more serious plots, but it's definitely not a horror game by any stretch.

We recently completed an in-game reboot with a new metaplot and new modteam. The setting is very malleable and defined by player choice, and is primarily about exploration and politics related to trying to build up a nation after a long era of war. We also have a regular event schedule with an itinerary posted at the start of every month and includes all the major events in that time, but with room for downtime in between; here's the one for March as an example.
