So, I like the core concept here, where PCs of a certain level can construct a bastion, with various modular facilities that they can add onto it, each of which expands the capabilities of the bastion in unique ways. I wish that the various Orders you can choose for the facilities were integrated into the existing Downtime system instead of having their own separate system of Bastion Turns, and that players had to make real choices about what to use their Bastion for each week, instead of being able to issue an Order to each facility each week. I’m also not so keen on Bastion Points, which feel too disconnected from anything concrete in the fictional world for my tastes.
I really like that the players have the option to draw their own map of their bastion, with each facility getting an allotment of square feet. Although I think a lot of players would pass on that, I know at least some will get really into it. Although I’m sure it’s a pipe dream, the idea is inspiring visions of an almost RTS-like campaign, where players eventually expand their bastions into veritable dungeons, within which they play the role of DM for other players who’s characters seek to raid them.
