Playing monstrous creatures

wow i am dense and bad at spelling.
the meaning of your quotes around 'fun' are lost on me, is it meant to be ironic or what?

yeah that's pretty much the idea. lore, world building and rules are all fine and very necessary things to have but if they get in the way of the fun then they have become roadblocks that must be smashed with the mightiest of smashing implements. if a game isn't fun or in some other way enjoyable for everyone it soon becomes a chore, interest wains and it withers and dies. I've had/been in to many games that died because of that so now i take great pains to avoid the pitfalls and perils that have killed games before.

How are centaurs fluffed in that campaign? Are they vulnerable to the Undead Curse?

They can fuck off. I am so sick of these fucking niggers who think they are allowed to play whatever they want in my campaigns. No, your shitty tengu is not allowed. No, your ratfolk is not allowed. No, your catfolk is not allowed. No, your tiefling is not allowed: that is a literal fucking demonspawn. Why the fuck would that be allowed in any campaign, let alone this one? No, you cannot play a drow. You will be shot on sight on the surface. Half these fuckers don't even read Drizz't so they have no excuse for wanting to play a drow, besides "lol it's different." Fuck different. Here's the thing: your race is the most boring fucking part of your character. Unless you do something interesting with it (which 90% of these stupid cunts don't do), then you are just weighing down the game. When you have a thri-keen, some homebrew furry shit, a tiefling and some fuck who wants to play kender, you know what? Fuck this. I made a setting that actually feels somewhat like the real world because it doesn't have 90 different races running around like it's motherfucking Mos Eisley cantina. It's not my fault that YOU are a bad roleplayer who can't be satisfied playing something out of the core book. Create an interesting character, and you can play as a human for the rest of your RPG career. I had groups that were entirely human yet they had personalities that seemed like real people. But no, no one wants to lump in 30 homebrew races plus 60 official wizards of the coast crapshit races they pump out like chocolate because they know it will keep people entertained and requires zero effort on their part. No DM worth shit wants to spend hours and hours putting that in his world. Play. A. Fucking. Human. You need to EARN the privilege of playing another race, by proving you can competently play a normal character first. You don't get the big boy toys until your prove you can be responsible for them.

stale pasta is stale

I don't have a problem with it unless it is unfair for balance reasons. In that case you can just play an immature version and make it weaker.

Not to be that guy, but this is one of the reasons I don't much like Dungeons and Dragons. It makes stuff like this a lot more complicated.

Why does it think humans so important? Humans interesting, yes! Weird, so weird, do all kinds of weird things. Consume so much liquid. But humans are not important, no. Don't taste good, either. We watch because humans are interesting, not because humans important.
It thinks it is clever, with its anger and hate and funny words, but we are cleverer, yes. It should leave and consume liquids before it gets thirsty.

"huuuuuuuuu my homebrew game is so simple and clean and elegant huuuuuuuuuuu"

fuck off, piss-rat.

I don't usually do it, but I see no problem with it if it fits the setting.

>Do you let them or do you tell them to fuck off?

Depends on setting and tone.

>If you let them do you create "realistic" reactions from the NPCs the party meets?

Yes, though the realistic reaction will change from setting to setting.

I've only played a monstrous race once, when the DM/player pair that designed the setting clearly wanted someone to run one of their beast races. I played a minotaur, it was pretty fun.

None of those are overpowered, so, no prob.
