Like, for example, my first game (Angel Beats Mafia) was relatively tame with one curveball thrown in. (Self-Reviving Serial Killer Lovers lol, though if you get past the name they were a relatively weak pair of roles too.)
I had a fairly good reputation and it helped that mafia was generally more active back then so people played my game and enjoyed it.
That made people come back for my second game (Rewrite), which was similar to the first in that most of the roles were relatively tame (VTs ahoy!), and it was largely successful too.
Of course, both games had their flaws but people enjoyed them overall which led to my third game. (Medaka Box Mafia)
I took a bit more of an experimental approach in my third game but people still joined it since my first and second games had been good enough.
So, basically, it might be prudent to get more experience under your belt before you go wild with modifying the mechanics of the game too much or something.
On an unrelated note, you people should be totally hyped for Ys Mafia when it comes around.
Totally balanced (Kittan Seal of Approval?), and totally unique. (Read: Not role madness, not bastard, completely awesome)
A once in a lifetime game of mafia, if you will.
Warning - while you were typing a new reply has been posted. You may wish to review your post.Your preconceptions may not be valid. This game sounds fun to me and I would play it if I weren't running it.
That could be totally correct. However I, personally, tend to shy away from games that I feel depart from the base game too much.
Other people might love it though. Who knows? Pester people into joining your game, pull favours, all that jazz.
