Personally I definitely wouldn't exchange the actual game plot for something like this but I do like how well such a seemingly whacky crack idea works in context.

I was hoping the founders dlc would build up on the past in that way exactly until they showed us that Shulk and Rex would be playable, after that I predicted correctly all the ways in which the DLC would fall short for me lol. I wish we'd gotten another Torna level DLC, man.
