In terms of theme and plot, cyberpunk has the most appeal to me. I've never seen a good porn game in that setting though. The world building in things like Neuromancer and Shadowrun is out of his world! I would love to see some game that uses cyber implants for mind control and sex slavery and shit.
Well I’m making a Cyberpunk one so that’s obviously my number one preference, but I’d also be interested in a really well made horror game. But I’d honestly be happy with more of anything that isn’t the typical, overdone modern setting.
Medieval (high fantasy), modern or sci-fi settings are all things that I really enjoy, but I really hope that the sex in the game and the gameplay are things that can keep my interest.
I like modern / Sci-fi settings, but I usually don’t like to suspend disbelief. It doesn’t always have to be hard Sci-Fi, but believability, plausibility, and logical consistency are very important to me.
