Which completely ignores the part where there's plenty of people who reinvent their characters just to be a part of your RP.[/quote]

No it doesn't. I just don't really consider a reinvented character to be a 'recycled' character, and more building a character from scratch using the same thematic root. Reusing themes, as you later go on to discuss in a later post, is perfectly fine by me. However, the manifestation of those themes is going to be different from RP to RP, depending on the content of those settings.

[quote=Kestrel]Liking a character and a setting aren't mutually exclusive either, and pre-made characters can easily add to your RP because that has more to do with the character's actions than whether a previous incarnation existed before your interest check went up or not.[/quote]

I'm not saying they can't necessarily add (though a badly-transposed character wouldn't); I just find the practice, as Prince has said, tends to bring a lot of inappropriate baggage with it that I'd rather avoid.

[quote=Kestrel]Hell, even if someone goes digging through RP's just to find a game where their character can fit, that doesn't automatically their only opinion on your setting is "That'll do." Especially not if they made big changes to your character. Maybe be it's more like "Your world looks so interesting, I want to add to it by inserting something I love and am proud of."[/quote]

That [i]is[/i] admittedly a nice way of looking at it. Unfortunately, that's just rarely the vibe I get when I read gleefully talking about "How they can use <insert name> for this."
When I see people doing this, I always get the impression that they're harking back to a dead RP when they had fun, which, at the 'accepting characters' stage, doesn't really fill a GM with confidence that the player's interest in the RP is 'legitimate', rather than an opportunity to briefly relive their previous experience.

[quote=Kestrel]And lastly; just like there's only so many archetypes in characters, the same goes for settings and worlds.You're probably not all that different.[/quote]

Yep, that's probably true, but I don't know what you're getting at.
