First things first: This is all my own personal experience.
Everyone roleplays differently. There is no single "correct" way to RP your character, and some of the best moments come from people doing things completely differently than I would.
That being said...
I was new once too.
I said a lot of dumb things.
I had no idea what people meant when they said "meta."
I tried way too hard to avoid certain words and made things harder on myself.
So this isn't meant to tell you how to play. It's meant to help you avoid some of the awkward moments, confusion, and sometimes even deaths that come from saying the wrong thing to the wrong person.
Because RP has a funny relationship with rules.
"RP is encouraged, but not required."
That does not mean every RPer is going to ignore things that break immersion.
I once told someone:
"RP is not required, but that doesn't mean an RPer won't shoot you in the face if you don't."
And honestly? I think that sums it up pretty well.
You are allowed to play however you want. You can say whatever you want.
But your choices have consequences.
If you walk up to someone and ask:
"Hey, can you tell me about the server?"
Some people will laugh and answer you.
Some people will ask what you mean.
Some people will shoot you and move on.
Personally? I wouldn't shoot someone for it.
But someone else might.
Welcome to RP.
