Kingdom Hearts 2 for PS2, which was released quite a few years ago, featured a world set in the original ENCOM grid where the main characters of KH2 take down the MCP. Last month," Kingdom Hearts 3D: Dream Drop Distance" for 3DS came out, and it has a game world set directly in the events of Legacy! It has light cycle races, disc v. keyblade battles, and all that good stuff! Clu and Rinzler are the villain characters. I was wondering if anybody else knew about this.
