Unless there are Roleplaying tournaments i dont see what other tournaments there are to organize besides Deathmatch. Deathmatching tournaments organized by SA-MP officials would have way more advertising and spread radius than any other tournament organized by any other DM community or entity. If it had anticheat support, which it should, then it would be even better and allow for people who generally dont take part in DM events to take part in it.
A football league type championship season would be for example one good type of event SA-MP could have, with one or more divisions depending on participation to determine who wins the title of that season's year.
Anyway now it's too late, DM is dead and it will die even more each day that passes, GTA 5 will be out for PC in a couple of months so part of the DM community which is still active nowadays will probably just leave to GTA 5 Online.

The thing is that the functions we needed for DM came out way too later than the functions RP scripts could use.
By the time we got some interesting functions for DM (0.3d+, despite of the speed change which completely changed the game) the RP scripters had more than enough time to cement their scripts with the functions that were out.

Obviously a RP can always be more polished, contain more features etc than a DM script, a DM script is meant to be plain and simple so it doesnt generate random lag where it isn't needed.
