So, we're just going to ignore the big impact that Call of Duty 4: Modern Warfare caused last gen? -- A game that released after Halo 3, caused Call of Duty's popularity to boom, and caused many new console shooters to release after it (trying to get a piece of the same success)?
Halo is never going to have the same impact as it did pre-2008. Too many popular console shooters to choose from now; multiplats at that (not exclusives). This was common sense well before Halo 5 released.

2007 was one of the biggest years in the last decade for shooters imo
Yes, COD was made before COD was copied. It still doesn't need to be copied and there have always been shooters there, even as much or more than today.
We can assume the change in gameplay and mechanics along with some other shooters becoming more popular is the reason for decline. We won't know for sure unless we get a new Halo made more like the old games without sprint.
I know you guys feel this stuff is standard but maybe a lot of people don't like sprint and cod style play more than you think
You guys want to argue that L4d and cod weren't popular enough to take away from Halo over those two years? maybe just maybe people actually like no sprint and halo style maps.... Maybe???
