I've got an idea for a game too. Star Wars: Battlefront 3.
Alright listen Activision buys the rights for star wars battlefront makes a COD style battlefront game, and adds a map maker to create your own planet to battle on. Space battles would start the way they did in SWBFII but they would continue through to the atmosphere as an LA-AT drops off squads of clones. Then your clone forces would battle their way through battalion, after battalion, after battalion, until they reach the command post. When they break through to the command post, their objective would be to take Grievous hostage. But they would soon realize that its impossible and Obi-Wan would break down the doors and battle General Grievous. Obi-Wan would gain the upperhand and Grievous would escape (unless that planet was Utapau) thus ending the chaotic battle. The best part is they would have to do at least 11 more levels (just because 12 is a good number for the final mission).
