Thanks for answers a lot! I didn't even thought that you check comments here and such. It is good to be mistaken, hehe.
1) There's some really good advice, but I was asking mainly about... how to run such a game, assuming that SBURB mostly about singleplayer exploration of the Land. But party has multiple players, so... How to manage spotlight between them and how to make things that affect multiple players at the time? It'll be good to have some knowlegde about it.
2) So it's basically making moves at misses and when nothing's going on?
Ahh. The answer to both questions is "PBTA systems are more player-driven than most systems." The consequences to most moves build their own drama, ideally, so the GM's main job is to set the tone, present situations, roll with the consequences of players' moves, and fill out the world with new stuff.
You might want to talk with potential players about what they want out of a game--if they want detailed singler-player exploration of their Lands, great! You can plan out some interesting locales. Play-by-post might be better for keeping that manageable/engaging.
But if they want the Homestuck experience--haphazard exploration regularly interrupted by shenanigans, game-breaking exploits, and text- or voice-chat conversations--then that's going to be a much more free-wheeling game. In that scenario I'd recruit my players to come up with ideas about the session, or even try the round-robin GMing approach so that everyone get to contribute equally.
Hmm... That explains a lot of things! Thank you for your answers and thank you for your game! It seems that this game really could translate the *feel* of Homestuck more than any other Homestuck tabletop game I've seen, what is absolutely awesome! :33
I'll definitely try run the game as my concerns about it are solved.
Oh, by the way! Do you know of any actual plays or you know, player/GM experience of the game? Just curious about how other people played it, if any.
