Well, Halo is still my favorite franchise even if I haven't played it in a few years. It's at least my favorite for the FPS genre. I don't anything in a FPS (maybe Far Cry for PC) had the impact that Halo had when I first played it on the Xbox. The franchise just gives an epic feel to everything it produces. Well, I finally got to see this: Halo Legends: Babysitter

I was not disappointed.

I'm not a huge fan of anime, but this was good. Again, the story ended with that nostalgic epic feeling that I got from the first Halo game. It was a sad ending, but if you've read the Halo novels then you already know how many Spartans fought and died during the war against the Covenant.

Here's a snippet of a review from Jesus at Couch Campus

The Halo Legends anthology is an toon adaptation of the Halo series consisting of seven short films animated by five different Japanese production houses. The Babysitter is the first installment of Halo Legends which was recently released on Halo Waypoint for a limited time.

Animated by Studio4°C, The Babysitter tells the story of four Helljumpers, sent on a mission to eliminate a key covenant prophet on a distant planet and to photograph ancient architecture that predates both the humans and the Covenants. Their biggest concern being the Spartan sent to accompany them on this mission. The Babysitter focuses on the rivalry between the Spartan-II Commandos and the ODST. http://www.couchcampus.com/2009/11/halo-legends-the-babysitter/

I suggest you read it all but it contains spoilers so be careful if you haven't seen it.

This video shows the coolness of the universe of Halo. I'm looking forward to the rest of the toons but I do have some gripes about this one. It was a bit bland looking, the detail wasn't really there and the color palette didn't do it for me. Massive gold blueprint. I thought maybe it was just a tad rushed? Don't know, but it could have been a bit longer and maybe just a tad deeper in story. My guess is that they are introducing these new Spartans so that later they may use them in games or video features. My guess is the Spartan in this toon will be in the new game Halo Reach.
