I'm gonna try and jam this thing back into a proper topic.
I question their claim that Combine are one of the most daunting armies on that list, but they're also high on it, so it's not that big a deal.
I'm actually rather curious as to how Reapers would handle something like the Zerg.
Armies mentioned already that weren't on the list, but I agree should have had a better showing: Heartless and Locust.
I'm not the biggest Gears fan, but I am a fan, and the Locust did blitz the shit out of humanity, so that's not a bad job. The Heartless have conquered multiple worlds.
Hey Moo, would Nobodies be worth mention as an army as well? I still haven't played through KH2 or anything after, so I might be missing some info, but the sheer quantity of heartless should stand that there's an equal number of Nobodies?
I honestly can't think of other armies, which I suppose says something. Then again, I'm tired as ****.
