I doubt if people will be feeling "unstoppable" after the next build, if I can ever get it to the point where it's release-ready. It's going to do something... unique... to deal with player power.
Exerelin and Uomoz's thing offer various flavors of station management, so yeah, there are multiple flavors of that out there. That said, the power factor feels about the same, it's just much, much slower because you're not able to grind as fast.
That, and if you've gotten up to the point where you're taking on Stations... IDK about you, but I rarely feel godlike taking those on, at least not if I have to care about profits. Even with super-ships and super-weapons, tanking through the center parts of Stations is pretty tough.
I think that the key issue there is that, by the time you can do that, you've amassed so much money from doing bounty missions that you're basically set, so I may start charging maintenance fees for ships past Destroyers or something to provide a higher money drain at higher levels or something
