Let me quote a PR Developer.
Not really. Our community is extremely happy with the outcome of the server license because if it wasn't for that, PR wouldn't be around today since it would have just been destroyed by server-side modding, which was starting to happen in the v0.5 release iirc where servers where changing the spawn times of vehicles, changing gameplay mechanics and many other things which was simply turning PR into vBF2 with new maps and more powerful weapons, which is not what we wanted it to be and not what our main community wanted to happen either.
Dont say it is just some gay control thing because even some of POE2's devs who thought it was a really bad idea for us to do what we where doing, later experienced server admins destroying there maps with what they where doing and one of the reasons why POE2 shut down afaik (thou not the main reason).
We dont spend countless hrs working on this mod just for some server admin to come along, take our work and with one fell swoop, destroy all our hard work. Our message for thous server admins who want to do that is if your not happy with our mod, make your own.
