This was a fun little game on NewGrounds' front page that I wanted to share:

I thought this would be a good inspirational model for porn developers. Not necessarily the repetition or mind fucking, but the combination of very low level game graphics with high level cutscene artwork seems like it would be a do-able level of work for small-time game developers and it totally works for a game like this.
The "writing" is also excellent. There's more focus on emotions and interactions than the usual heroic narrative. Even though it's scripted, there are some good "oh shit" moments that I usually only get from randomized games. This is not necessarily anything to do with porn, but I know people around here tend to prefer a more immersive experience and I think this is the way to do it.
