We entertained a few themes but due to unanimous feedback by classmates and tutor we ultimately decided to go with RPG Fantasy World + Nightclub. This will allow us to create a lot of fun playable character, enemy and environment designs by mixing the two. Combining these two themes will give us an additional USP as I haven't seen it being done before.
As far as the plot goes we aren't too sure as of yet. We know there will be a group of adventurers navigating through a dungeon (that is a Nightclub) with the goal of getting to the final floor. Perhaps there is a bad guy that they must defeat there in order to free the habitants of this world from his oppressive dance moves or maybe they just wanted to dance there.
It makes sense for this project to be a game that doesn't take itself too seriously due to the theme chosen. I also don't think adding extreme graphic depictions of violence, explicit sex scenes or frequent swearing would add anything to the game so no point in doing so.
