The problem is there are already a fair few browser based maffia games kicking around, one Vandettacrime even run by one of our established forum members, then there is x mafia, torn, etc. All games where you can do crimes, beat up and hospitalise other players, go to jail, form mob families etc.
How is the game your developing different? What sort of things would you do in the game?
Sorry to be negative here, I will confess that mafia and crime games are less my thing personally, so its entirely possible I have more of a downer on this project than others might.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
