Some cool ideas in here.
What about something with a sci-fi setting? There's a lot of sci-fi assets and that allows you to be as crazy with a story as you want, because you know future and sci-fi, plus introduce other races/characters.
Could be fun. Could be humans discovering space travel for the first time and visiting different worlds, could be a normal story in a sci-fi setting, etc.
I like a dark, mature, serious, sexy story so obviously something like that. But of course, those are only my tastes.
Keep up the good work. I've been messing around with Daz for a long time and have no coding or game to show for it
P.S. And of course, if being ultra self-ish, a parody of X-Men featuring Rogue especially, but alas I may have to do that myself. Love Oni's game but wish there was more actual content/scenes.
