I was recently inspired to try and write a game related to a wife-swap type scenario. I thought the social and mental aspects would be interesting, and I started working on a game where you were the (initially) reluctant husband in the scenario. Narrativly, it focuses on you slowly giving in to the desires - or deciding to walk away - and includes a lot of stuff relating to not only your hesitance, but the knowledge that your wife and best friend are nearby, and showing no such reluctance (including some voyeuristic aspects).
And, I was pretty jazzed! Lots of dialog, lots of new stuff to try (fuses, scripts, demons, etc)...
But I realized that, as I have it written (probably 2/3rds of the way done) it dumps you RIGHT into the intimacy, and concludes when you eventually leave.
BUT - though there is a lot of depth (I think), there is no puzzle, etc. Advancing the scene is just a matter of making choices that advance the scene logically (talking, touching eventually, etc).
Do people think such a thing is 'playable', or is it too flat to add much real value? What thoughts or advice do you have?
