I see a LOT of great ideas you've got listed, and I'd love to get into an RP with you and a group once again!
Here are the ideas you have listed that I'd be eager to jump into:
Brother's Grimm - I'd be more than happy to be your character's brother, or brother to whomever is the other Grimm in the story.
The Cursed Quest - I'd make a character that fit the rest of the party, filling a role that hopefully needs filling. I would like to avoid my character 'copy-catting' another character, whether accidentally or not.
Playboy's Delight - I'd be one of the two businessmen, more than happy to 'share' a delightful distraction with his playboy-buddy.
I accept your aims as usual, Darius, and your goals. As always, I am fine with M/M/F, as long as there is no expectation of my character participating in M/M activities. Nothing against it, but it's just not my style. I would definitely prefer some sort of story along with sexy-times, but I'd prefer a game where it wasn't 100% sex, nor 100% devoid of sex. Some happy medium would be what I would hope for.
Let me know if I can help out! :)
