It could be cool, I could easily manage the server with the same staff or different staff. It all depends if I get someone who's willing to script the server, Aleco or Chap would probably, but I'll talk to them about it.
Little missions would be cool to see. Like, proper races or car survival (when you have to get rid of all the players, and stay alive), was pretty famous on MTA for the first time.
Mini Missions are cool, should be some command implanted IG which only an admin could activate and it would teleport the people who would like to participate into a, SUMO challenge, race, hotel war, brawls.. etc.
Yeah, mini missions is awesome idea. There could be racing and other things like that. And no need for drift or stunt server then.
