I don't want it for a few reasons.
1. The game isn't that old, I could understand a Marathon remake but both Halo CE and Halo 2 are still playable, Halo CE had a decent reason to be remade for the anniversary, but there is no reason to remake Halo 2.
2. Remaking Halo 2 would just be making you pay more for a game that still works and looks fine, if you want a Halo 2 remake then just go and play Halo 2 and save your self some money.
3. I don't know how 343i thinks of Halo 2 but Bungie didn't even like to talk about it and considered the game a failure. This dramatically decreases the chance of a remake.
