My vision for the rogue like would be an infinitely large, procedurally generated minesweeper. The grind could be chunked into mega sqaures, and maybe when you clear a mega square, it reveals a number which is how close you are to a target destination.
There are so many ideas you can use with this concept.
What if the planets and the enemies couldn't be differentiated by the numbers right away, so you needed another tool to do that.
I'm just ranting at this point, maybe I'll steal some ideas later.
