I want to hug you. Ryker just strikes me as the tough-love type. I don't think he's trying to be mean|put people down. It is his way of being sincere and doing the right-thing|trying to make this place better ect. As far as player evaluations go, mafia is generally a game of luck, strategy, and emotional analysis. Not always the most cunning players win due to a lucky report so on and so forth.
As far as reading other players go, if you play with the same players over and over again and win repeatedly then you're really good at reading|deceiving that close-knit group of people. How much of an accomplishment that is? I suppose that's up to the individuals themselves. Now if you play on a number of mafia sites and you're good at the game, then I suppose you're generally good at lying and|or figuring out when other people are lying.
I think that being bad|good at a game isn't incredibly important in the grand scheme of things. Then again I am on a competitive gaming site, so perhaps I'm the one who is out of place when putting these things into perspective~ :33
