Well, I'm not sure there's many that want them to just give up on the series even if they didn't like Halo 5.
Whereas I think there's plenty of people that don't want Metal Gear without Kojima at the helm. I dunno.
DMC and MGS are the two from the poll I think are most likely.
I'd personally like 343 to step away from Halo. If Halo 6 is anything like 5 I'll be skipping it. 343 seems to have figured out the competitive scene, but not how to structure a great single-player campaign, which is more important to me.
