But I'll probably only choose from those who have run more than one game.
Toriychik has some pretty interesting settings. Revanko does too, and the atmosphere is great. For example, Zybr is good at creating mafia games about gangster groups (although I get annoyed by some aspects of his GMing, like the displayed blocks as it was recently, you know what I mean). I don't remember Vegtam's mafia games very well, nor Magnus's.
In short, I'm voting for Nebo.
If I had to choose the BEST PLAYER, I wouldn't even know, I'll just list all the "cool" ones.
I've never liked Gilts' games from the point of view of... beauty and fun. Never means "never," not after SAYUZ. Too simple, too boring, zero dialogues, the city is just about executions, I've analyzed it, believe me. He's strong, but that's not important.
Hossi has too much "ololoshka" (nonsense)! I personally get very annoyed when I have to talk to him (at least before, I don't remember any major discussions in the mafia games lately), it's anti-fun! Although it's funny in some ways. So I won't vote for Hossi.
Toriychik is too laconic; there's no discussion with him at all. SO I WON'T VOTE FOR HIM EITHER!
I didn't know who to choose, but let it be Morning, he's good and cool overall.
Except the ones we've made
