Re: Popularity of players playing already created characters?
I have taken over characters a few times, and if the game was going well, and continued to do so, the character did too. In one case the original player hadn't developed the character much, so aside from class I had pretty much a free hand. Another I tweaked a little to make her more suited to my style of play, and yet another was on condition that I changed her personality! For one thing, she was in the habit of dressing in mostly transparent draperies, and then getting upset when males noticed. What's the point of showing off like that, if not wanting to be noticed?? It was pretty much required where she came from, but not the custom where she was now - and I'm pretty sure where she came from guys looked too, they just knew not to touch without more overt invitation. Besides that her attitude was not one of the cooperation needed in a PC party.
The first game didn't last long, IIRC, I think some of the other players were also not sufficiently invested to develop detailed characters, or play consistently. The second lasted quite a while, and I also played in at least one more of the GM's set of four related games, until his circumstances changed, and he gradually played less and less until he disappeared.
The third petered out eventually but did run for a while through the next part of the plot.
I can't imagine taking over a character that I was not allowed to change at least a little, unless by some miracle it already suited me, but it certainly can work.
