Honestly, doc/watcher/similar protective roles are a necessary evil in the game. While they do allow bad play to slip by in one sense, they also create a situation where mafia is forced to decide it's night actions with the consideration "what if a doc/watcher protected this target?"
This ultimately refers back to the negative feedback issue of, "if I'm doing well, mafia is gonna kill me", and therefore discourages people from playing well. Also there's the all too common issue in irl life mafia of "you're not dead yet, you're good at the game, therefore you're mafia".
This more true of the doc then the watcher, but the possibility of the doc existing improves the game a lot more then it hurts it, there's a reason that no mafiascum mountainous games have been won by town to date, and I just don't think mountainous is a good game type due to the ability of mafia to just snipe anyway whose doing well, you reach a point where in order to be balanced, you have to make it so town-favored technically that town is just better off random-lynching because nobody's personal winrate is gonna surpass the success of random-lynching.
Didn't OS run an all-VT game, and everyone hated it?
No, he ran a game with tons of chance-based roles, and it was stupid.
I think running more simple, open and largely vanilla setups like Jungle Republic, Fire and Ice, TWEWY or Portal would be pretty cool, but most mods would rather run set-ups they've created rather than simple games like those
It's not hard to make unique setups with interesting power roles without subverting the basic mechanic that makes mafia interesting.
Because pure VT games are nothing but guesswork until they catch a scum and mostly-VT games get stale after awhile. The strategies become redundant and there's no real variance in PRs.
Don't get me wrong, I think DGames could stand to be a bit more vanilla, but not that much.
Except that's not true, what makes it interesting is that like a good competative game, you're competing against somebody's mind, or multiple people's minds.
The human mind is infinitely complex and every situation is markedly different. That's what allows you to continuously replay smash but makes most singleplayer games get boring after a few times. The human mind is always a new challenge, even if it's somebody overall weaker then you.
Mafia has the same basic appeals as a competitive game.
Smash to Mafia correlation isn't very good.
Basic mafia is boring online but a lot more fun irl.
It's cause you're bad at mafia brah.
I kid I kid, but I think it definitely does suggest a more casual approach to the game, in the same way people who prefer all items matches 4 players on hyrule temple do. It's the value of the spectacle as opposed to the value of competing versus another player's mind.
