Familiar with abject art?
What if you had to make a game from the refuse, the garbage, the cast offs of other games or other game processes? What if levels, animations, avatars, text and code that were deemed not suitable or were merely byproducts of another process were instead elevated to a main game instead?
This is the refuse of Twilight Imperium 3rd Edition. I wonder what kind of game this could be. When I finish my present series of six, it seems like an interesting challenge to consider.
