I bought this game, finished it, and reviewed it. I really think it was nice to have a huge ambitious fan project like this on the Genesis, but I had problems with the game itself. It felt like you never got enough EXP and some of the writing was downright weird.
I'm with the OP though. Although I personally am a little bummed to see this game ported to so many platforms, I still respect that Watermelon is delivering new games to play on our old hardware at all. The idea of the beat em' up or whatever they have planned for the SNES has me very interested. I think that would be a much easier project for them to deliver on than a RPG the scale of Pier Solar was.
