So I've been kicking around the idea for a crossover RPG storyline between multiple different tapastic characters plus a few other of my friends' stories that aren't on Tapastic yet at the moment and I was thinking it would be fun to write a rough treatment for the story I had in mind in that regard.
Just one problem, I need characters to write that hypothetical crossover story treatment.
I have a general idea of what roster of characters I want for the crossover story, but I'm wondering if I should ask their writers' permission first before actually writing it, or should i just write it anyways and then just show it to the people whose characters I used?
I'm a bit stuck on this because I'm not planning on publishing said story proper, it would be more of a fun sort of experiment and creative break to stretch my "muscles" so to speak and I'd probably only show it to the friends whose characters I used for it for their thoughts on the story treatment.
How should I go about it? should I ask the peoples' permission for using their characters first before writing this hypothetical script? Or write it with the characters I had in mind and show it to them later? What would you guys do regarding this?
Thanks again for the help in that regard.
