Granted I dont know how exactly it works, but why not just pull it out and make it a stand alone instead of a conversion. It sounds like every patch you guys write you have to rewrite prims code to accept it. Make us a separate game, stop loading base code then rewriting it with prim when we log in (gives us the load time) just load prim, and pull us from the normal update pool.
The fast (normal) load time will get the population up, you guys can stop having to mess with writing specific updates for 100 to 200 players every patch and we can finally have a chance to grow as a game type.
Prim is the in between from official and unofficial, the reason there are thousands of unofficial servers is cause the massive difference between the powerful and the new on normal servers. On prim that difference is cut down amazingly small. Several times on our cluster streamers have came in and within two weeks have wiped everyone, it's just dinos here.
Cut us out, let our population grow, and give us a dev when it does. Prim is the best game type even with it taking as long as it does to load and the only dev love besides you guys having to fix it every patch it seems was one year ago this month.
Plus think with you getting to stop recoding every patch you put out you could just spend a fraction of that time just coding to give prim it's own updates every few months.
I think this option will keep us from getting wiped... will lessen your work load, and will give prim its first chance at actually being a supported game type (outside of the fact you guys have been spending time every patch to keep it up....)
