Halo is a game series that can continue for years to come. Besides the good ideas for RTS games, FPS games can help tell the stories of the individaul battles during the war with the Covenant. I would like to see a game where you are a marine or shock trooper and your on one or multiple colonies, where you learn about the history of the war and slowly learn more and more about the SPARTAN program.But, bungie or microsoft, which ever owns the rights, should do a Forerunner game with master chief. With the new technologies coming out for games, like completely destructable surroundings or having the ability to battle hundreds of enemies in the game at once, should make for fun and exciting halo FPS games. I'm a big advocate of Halo cause the first one is the reason why I got back into video games.
