I talked about player participation once, and made a separate tab explaining how players can contribute to the game (make sure you read it!)
I'll say that the current level of participation is not as high as I wanted/expected, but that's ok. On the other hand, the impact that this participation is having on the game is big.
On a rough count, there are at least 7 scenes/events on the game that were directly inspired from things posted on the Bathroom Wall (like TD: I want to turn a man into a woman, and then into a statue.), not counting more general things that would be in the game anyway but were also referred to there, like BDSM and trannies.
I got a few photos of naked players by e-mail, and a few half-naked photos of friends who wanted a cameo, not counting pictures of unknowing friends.
There are a few direct quotes from people (friends, internet people) used in the game as well.
I got a few e-mails of people volunteering to testing, which is great, but nothing near the 100 testers I need. I have some ideas on how to get more testers, but I'll save them until I really need it.
My goal with this is adding another level of player interaction on the game. It is part of the game's concept. So, unless you're an unsexualized robot, please contribute!
Polymorphous Perversity should be complete within a couple of months.
