Thought I write some basics to roleplay that I WAS TAUGHT/GO BY. Again, this is what i use. These are not set in stone, just personally used as my rule-of-thumb.
- Godmodding is having a character who is uber strong and zero weakness that cannot be killed. Everything can die. Even you.
- Metagaming is using Out-of-Character (OOC) information In-Character (IC). Just because you are aware of the information does NOT mean your character does.
Third. YOU are NOT your character. So don't take crap personal if something happens IC, such as insults.
Fourth.... Your character has limits, whether physical or mental. Example is sprinting for days straight and completely fine and no fatigue. Limits keep you from Godmodding.
Thats all I can think of right now. Help it helps.
