I was toying with another idea after I made my post: An rpg where there is one fighty guy who does all the fighting and everyone else is an investigate or other non-combat role, along the lines of, say, Captain Planet or Lord of the Rings. Lord of the Rings is the classic example here, since you have three guys who literally have nothing to do when combat starts. If I were playing Merry or Pippin, I would not even bother turning up to sessions, seriously.
I think once you hit a certain number of players, the GM has a responsibility to make sure everyone is involved. Captain Planet is a surprisingly good example, since it hits on something I was thinking about earlier. Suppose you have a game with a very large number of players, to the point where RP scenes are great, but story scenes drag. Why not allocate everyone a non-combat role, for handling investigations, roleplaying and party discussion scenes, but when the plot needs to move ahead, you do the unthinkable and give them group control over a single PC, who is not only the guy who handles the fight scenes, but also moves the plot ahead.
Now that I've had the idea, I really want to try it for my next rpg. Encourage everyone to make a fun, interesting character for PC interaction and then have them share a character when they need to get shit done. There's less static, combats would go faster, everybody's happy. But at this point, I bet someone is thinking that is a totally implausible idea and would never work, to which I say, [spoiler]combining giant robots a la Power Rangers/Voltron.[/spoiler] I am honestly surprised I didn't think of it sooner.
Anyway, the theory should be applicable to other genres, but probably not as easily. I think a solution for speeding up online games could be hit on, though, with a bit of work.
Frocto, if you ran a Berserk game I would love you forever. Like, seriously. Serious.
After my last online rpg, where only three of the five players turned up to the
first session, I am honestly a little leary of online games right now. Still, I could see if Lee-Ham and Meikai were up for something, since they are basically my dependable rpg homies currently. ALSO I AM NOT MUCH OF A FANTASY GM, AS HAS BEEN DOCUMENTED. Feel free to hit me up on Aim if you want to toss some ideas back and forth.
