I have an idea for a pokemon game called Pokemon Spiritual Version.The starters are ghost,dark and psychic types.It takes place in the Oracol region.It's mascot is either Darkrai,Girantina or Sisate,the opposite of Arceus.The evil team in it is Team Shadow.They specialize in ghost and dark types.The gyms are ghost,electric,phycic,dragon,poison,dark and rock type gyms.The Elite 4 specialize in ghost,poison,dragon and flying types.If I can improve on something,please tell me.Hope you like it.
Well there are two places where you can post this:
This thread about what Pokemon game you would make, if it's just a fun idea.
If not, somewhere in the Game Development/ROM Hacking section, if you plan to make it. I'm not too familiar with those sections though, be sure to read the rules if you intend to post there!
