I'm not sure about this one... on the one hand, I loved Halo: CE and it could be cool to see all the features of the game I loved remastered and updated into a new era. They may even revamp the plot a little by giving a major antagonistic role to the future Arbiter Thel Vadam, which would be cool.
But on the other hand, Halo CE was a great game. And one that needed no recreation, as it still stands up quite well to the modern standards of shooters to this day. I don't need to buy the whole game again for nostalgia's sake. Plus if I'm not allowed to play as an Elite in multiplayer, I'd go nuts.
So to be honest, I might have to think about this a lot more before I make up my mind.
Which is the same policy I'm using for this whole Halo 4 business. Right now, I'm on the fence.
