Putting tons of hybrid cars on the ground (with the included extra huge batteries and short life spans such batteries dictate) is not the answer. Cows that burp less (WTF?) is not the answer.
True. The real solution is to have less cars on the road in general and to raise fewer cows.
Reduce,Reuse,Recycle... In that order. Global warming or not, reduction of everything that polutes and/or excessively consumes resources should be the goal.
Assuming they did not rip off too much, they should just rename the game, characters, locations, redraw the character sprites so they bare no resemblance and then release like that. If they are still not happy and are feeling daring, they can later "leak" a patch which changes everything back to as it was originally intended.
It was a Chrono Trigger rom hack. Removing all Square-Enix IP would be starting from scratch, thus not really a viable option.
Your good nature will bring you unbounded happiness.
