as a long time player, i have been showing my loyalty to this game. last time i reviewed this game with 5 stars was 1/17/15, like eleven years ago. so i think i have to say this: there's a map in Roblox that copying your game called Idle Mafia Game. go look up for yourself, from bank, to properties, to crews, to stats, to jobs, all of it. i used to play Mafia Wars back in Facebook, but it wasn't similar to that. this Roblox game literally copying your game smh, look it up!

I've been playing this game for over 10 years. its always been a bad experience with support no matter who owned this game. I have a galaxy z fold 8 ultra and the game hasn't been working on my phone. I've tried to contact support every way fellow players told me whether its been through discord, facebook,and/or email. its been a week and I haven't heard anything. so if you run into a problem dont expect support to be Any help or compensate if you missed out on anything

I've been playing this game for years, it seems I always come back for more. That changed after this last server outage my character class was reset from assassin to enforcer, but only for clan battles. There's no way to reset it, and no way in the app to contact customer support, so I'm done playing. Thanks for all the good years, good luck on whatever issues you're struggling with.
