Yes, most competition wins are questionable. But so are the Olympic Games, the Football World Cup, the Formula1, whatever. Someone or a team wins in the end, and it depends on many things. Small decisions, current concentration, whatever. But does it mean that all the others were bad? Of course not. Germany won the FootBall World Cup last year and it's clear that they were the best. (Not only because I'm a fan, lol.) Four years before, Spain won. Were they the best team? Who knows? They were good but so were quite a couple of other teams. (They were surely better than Germany, unfortunately.) Eight years before, Italy. Wellshyt. I don't think they deserved it at all, but they still won.
Does it have to do anything with Mafia?
A lot.
It's about plenty of things. Let me name you some.
IRL issues. Something terrible/tiring/important/etc. happens and you lose focus or you have to replace out. Even a bad day could lead to a horrible post and bang, you're history.
Focus. Just as the previous. Everyone is dedicated to win but what if someone reads and posts less for a time because of being busy, whereas someone else has an unexpected free evening to play?
Scumteams. Some players can work together as a scumteam like a dream, while others simply "don't feel each other", even if each of them are good at being scum... normally.
Meta, previous experience, whatever. Eg. one single player posting "I know him/her well and that's his/her townplay", convincing others ...and a scum gets a couple of Days. Or a town gets mislynched.
Role distrubution. Wellshyt. Gods be merciful to the town if I draw town-Vig. ^_^ In other words: what if that PR had gone to someone else...?
Butterflies. Not only lucky events like pressurizing a scum early-Day1 or Nightkilling a PR Night1. It's more. Someone is spared at Night because he/she's misreading the whole game... but then a team member dies in another game, starts reading and guesses the obvtown-looking scum right...
I think Trojan's analogy about Bridge nails it. (I used to play Bridge a lot long ago.)
689.
Also, I'm unwilling to feel bad just because we won.
Mostly because I think if another team had won, some players would be upset about it too. Maybe other players, but the story would be the same.
(Plus, something else. We'd known the rules before Team Mafia started. I know it's easy to say but I wouldn't be upset if anyone else had won. Even if I know that it annoys a couple of players now. To tell the truth, I was just as annoyed when I saw the results of the Setup Competition. A 4th place for Matrix 14?! But I'd worked a lot on it! After getting known the details via PM I understood that I had missed the rules for getting points. Eigh, "Originality" had a score too, aaaand Matrix 14 is everything but original, lol.)
Could we have a "more objective" system. Well yes........ if there were, say, 3 games for each player, detailed scoring for team efforts, spectacular actions, remaining members of a team, blah, blah. It would be horrible to handle it and there might be other issues, I suppose.
Nevertheless, I learnt a lot from my game and from the games I read too, and I think this is true for many of us.
