This topic was inspired by @MissQ's comment in I'm so tired of.... I am sure it has been touched on in other topics or might have been a topic all on its own at some point (a search did not turn up any results though). Although some ranting and venting is okay, that's not the purpose of this topic. The questions are just guidelines. Please don't think you need to answer all of them or answer them in order. They can be combined, ignored, etc. This is a free-for-all discussion for fun and elucidation. I'll weigh in with my thoughts once we get going.
What character concepts do you love?
What traits make you avoid a specific type of character?
What are your character concept preferences when you create a new character? Please clarify if genre-specific.
What traits and concepts do you prefer RPing with (perhaps opposite the type of character you are writing)?
When looking over a new RPG to join, what do you need to see to make you drool over creating a character? [Clarification: based on active character profiles, wanteds, etc.]
