The first Halo Wars was kind of boring to me, but it might be entertaining to see what this one has in-store.
Also, what games do you own? I'm a big Halo head, so I'm steady on MCC; I get on H5 sometimes too. Rocket League is a great game to own as well. If you can find a group of people to play with, there is this free game called ROBLOX.
I'm waiting for BO1 & Skate 3 backwards compatibility.
