The game would be a kinda rpg-lite adventure game.
It would be similar to the POP and UC and TR games.
You would explore Bara-Magna, fight beasts, buy upgrades, find secrets and ride mounts, to complete a story that coinicdes with the main story.
The Character you would play as would be exclusive to the game and you would get his helmet with the game, you would also be told a code in-game that when entered into LEGO club would give you instructions on how to build him. (He would be made up of other 09 sets.)
I would post more...but I can't be bothered (I'm really worn out today) So myabe later/tomorrow.
I guess it would be on PS3 and Xbox 360 and would have craptastic versions for PS2 and Wii.
The PS3 version would be the best though.
