Halo wars would have been perfect
Even though I agree with you about Wars being a better idea for a gift, I would want the game fixed before they added Wars. With ODST being added that tells me that they can add to the MCC. Which gives me hope that Wars and Reach will be added as well making MCC a hub for all the past games.
Most of us are getting ODST for free for compensation, and even then they didn’t have to go this far as to port ODST to the xbox one in the first place. While it would be cool to get Reach and Wars over to the xbox one at some point, they already are doing ODST, so I am happy.
Halo wars is freaking awesome
Halo wars was pretty different from what they normally do but so fun to play, it would be nice for them if anything to just add it to the collection for all.
