10. All of the spinoffs

Zack: I enjoyed Halo Wars and its sequel, but they were never Halo-enough for many. Meanwhile, I hated the top down spin-offs because they were so damn boring. And the arcade game was fine, but I don’t enjoy the turret controllers modern light gun shooters use, so it too is banished to the bottom of our list.
Ari: The phrase “top-down spin-offs” makes me wanna hurl. And from what I’ve played of Halo Wars, those games seem neat, and I see how they’d click with fans of the RTS genre. But c’mon, the best Halo games give you a gun, a super suit, a bunch of long gray hallways, and an endless horde of space aliens for you to mow down.
