Well, Tin/Steel Versions are two games that introduce 151-251 new pokemon (much like what X/Y is doing this October) and it contains a new story, new characters and more! for more info head to http://www.pokecommunity.com/showthread.php?t=254225&highlight=tin%2Fsteel. This link tells you what I've initially wanted to do. I've made updates offline but I want to get back and create this game since there's a team that could help now :)
