I am looking to make my own cartoon someday, but in the mean time, I like to work on a side project that is a fan work of Dragon Ball. If you want to see it, than check out this link

If you have any questions about it, you can ask 'em in the forum or E-mail me.
I think matchmaking would end up being a misreable experience, because random people being paired together in Firefight, will probably not work together all that well, and if they do, well than it's just pure luck or a combination of great players.
I do feel the Campaign was somewhat short. However, shortness is easily overcome by replayability. What I feel would have made the campaign funner is different modes of play, other than just skulls and whatnot, with different objectives and competitive play, like a timed mode that effects more than your score as time elapses, or a competitive campaign where each player is trying to outdue the other, or a version of campaign mode where you have lives, etc.
of course if you added stuff like that, you'd want to add subtance to the campaigns, like alternate routes and having the levels change each time.....I guess implement some of the level concepts from Left4Dead 2....and a few other titles.
all in all, it's still fun and worth replaying anyway, but like any game, it could always be better. had they had more time and budget for the game, I'm sure it would have been far better, but I suppose the choice to convert it from a add-on to a title was last minute, they didn't have time to make it like Halo 3's other brother, and it's instead more like Halo 3's Sidekick. Still a good game, but I really wish it wasn't full retail price, I have a hard enough time paying for gas, I don't want to pay another 60 bucks when I can't even afford Xbox Live
