Hmm. It'd be some combination of Kingdom Hearts, Pokemon and Legend of Zelda games. Also it'd have moogles in. And numerous cute creatures. It'd have a lot of sidequests and secrets to uncover.

Part of it'd be sorta like a town and you had to help people out by completing various quests, so there'd be a lot of exploring. It wouldn't be too difficult though. The basic game would be easy enough but there'd be so many different optional challenges, that you could get as much difficulty out of the game as you wished.

There would be battles like Kingdom Hearts style, your character being able to jump, slash, etc and the battles wouldn't be random. There would be bosses too but they would be optional for getting extra stuff, maybe. The game's main challenge wouldn't come from the bosses you killed but mostly the level of exploration and numerous quests you could complete.

In the game you can go at your own pace, and you can do things in different orders, so it's quite non-linear.

Also the game would be designed so you get a different playing experience, or that different players get different experiences depending on the choices they make. Also these things effect how the story turns out. So maybe numerous endings. But always happy endings. There would probably be an underlying love story or something, but it wouldn't be all sickly and in your face, it'd be something like Zidane and Garnet. (Well how I personally think their story worked).

And it'd be addictive because there'd be so much to do and uncover. I'm not sure what platform it'd be on. GBA or Gamecube maybe. Probably Gamecube. Ohh yeah I know it'd be on Gamecube and you can link your GBA up, and then the side thing going on on your GBA will be the bit that is similar to Pokemon, like you'd have a "pokedex" type thing with the creatures you collect, you can also access them from the GBA to colour them and stuff. So you collect more creatures from every area you go to, and so the more sidequests or optional areas you decide to complete, the more of these creatures you can find. And also they will help you with other quests... and they'd all be really cute. ^_^

Yeah, I could probably go on forever, but you get the point. xD
