IMHO, the chance that a Jag programmer has a really unique idea is close to zero, since there are so few of them and even nearly every PC game published today is just a re-implementation of games done dozens if not hundred times before (OK, "Portal" brought something really unique to the 1st person genre, but also this title was based on another title: Narbacular Drop).
So instead of new ideas, I hope for people coming up with good implementations of old ones (e.g. take platformers like Gods, Lionheart, Deliverance, Leander, Baal, Turrican, etc. pp. and blend the best parts of these into one single title with graphics and sound accodring to the Jaguar's capabilities).
Same with 3D Jump'n'Runs (although i would like to see one with a rat as the main character - though I'm not in favour of the artificial cuteness of Remy, I'd like a more realistic look), arcade-style shmups, etc..

my point is to create your own game is better as a simple port. i like ports of good games, too (worms e.g.).
but a nice remake, an improved(!) turrican or something, is far prior over that and a very cool thing. it´s not necessary to create milestones in games history, but a simple 1:1 port is not what the jag needs in first place.
