Limits that DM's give players

But.. user GM... I want to play as Bitmuff Scruff-Rubber, see look it's in the Handbook of Humanoids!

>my friend is always our DM and he denied a new player from being a furry

Never allows
>furries
>trans or some weird gender
>scalies
>skimpy clothes

I'd say he's a 7/10 GM but do you see problems with those limits?

Good. He is doing the Emperor's work

My stance is that a player can play what ever they choose so long as it fits the setting, they have proven that they can do so in a way that is mature and unobtrusive to the other players.

I would actually go further

GM is doing everything right

what counts as scalies?
I like lizard people.

This.

GM is missing out on Lizardfolk. Which should be the only tolerated beast race. They dont/ shouldn't have tits. Shouldnt be wanting to fuck, due to the reptilian genitalia and only doing it for reproduction.
You're just a lizard dood, trying to get a permanent heat spell on all your gear.

No chicks and no autocannons.
