The game is really great. But there are several issues. First of all, in the more recent update, the game has been pretty buggy for several users. I'm sure they'll end up fixing it though. Secondly, the game has some not so great people. I mean if you've been on the Mafia42 reddit then you've probably seen some posts about certain people. Thirdly, some of the skills for cards are absolutely overpowered. It adds a P2W aspect to the game. There are several other problems with this game too.

Great game, good mechanics. It actually makes you think and analyze everyone to win, gets hard when you are a novice but I personally like the fact that new people can get mentors to help them get better though the only problem I have is that in the novice channel, some rooms are only for chatting so it's kinda hard to find a room to play since most times they are full but besides that, good game

i really like this game theres so much that can be done with it but theres a huge problem. The players, the community is absolutely anti rookie and because the learning curve of the game is huge no one is willing to help you and the tutorials are vague, other players will report ur profile for not being up to their standard and verbally harrass u because there is no speck of cencorship, its also extreme p2w to get good cards. if u are looking to have a good time dont leave novice channel. ever.
