halo 4 will be a game, obviously, since halo 3 was a game, and halo 2 was a game, and halo 1 was a game....why would halo 4 NOT be a game?
Oh and, FYI, halo is NOT the best game of the century, to say that is so ignorant, it's like saying that some invention from 1907 is the best thing of the century. For all you know, this century will see so many new games, they will easily trump halo, not to mention that its more then likely virtual reality will be fully implemented later this century, and no one will even remember what halo was when they are fully immersed in some game like in the dot hack series, (not as retarded though, and minus the overly-stupid virus thing)
Also, some people may think there are better games out right now then halo, though it is valid to say it's one of, if not the most recognised and over-hyped series, that is true. When I say over-hyped, I don't mean as an insult, but Halo 3 really is over-hyped, it's recieved too much attention, like taking a can of sugar and dumping it into a small cup of tea rather then putting in a few tea-spoons.
Based on how much money Bungie is making from the Halo 3 game, they should buy back the rights from microsoft, seriously, micro-tard needs to go jack some other series. They are good and all, but they are greedy as **** and like to steal things.
