I was wondering if one of our stalwart hack creators could make a game in a kind of nuzlocke mode. Perhaps you could have no access to a pokecentre. Each town instead has a free elixer dispenser so you can top up your PP, a pokemart for medicines and a poke graveyard to drop of the deceased. All healing up and recovery must be done via medicines from the mart. This would certainly make any game very challenging. A player would have to decide on how to spend any money very wisely (pokeballs or medicine?).
It might also be kind of interesting if a points scoring system could be adopted. Points for trainer battles, gym badges, efficiency of event completion. Points deducted for fainted pokemon. This could add an extra competitive edge to the games.
Its probably been suggested, but how about playing a game where pokemon super effective against a gym are banned from entry. So for example if you no ground pokemon allowed in an electric gym, no water or rock types in a fire gym and so forth.
