I'd love a parody game of JRPG tropes, to be honest. Something along the lines of 3D Dot Game Heroes, but one that doesn't lose steam with the humor and the outdated gameplay after a few dungeons.
It's called Half-Minute Hero, though it is probably more in the lines of retro JRPG parody.
Then again, it is in the eye of the beholder. I could easily see something like Xenogears as a parody in itself, but that's just part of the charm.
