Because it's way too recycled. People talk trash to CoD(I'm not a fanboy of cod) saying that it's the same exact thing every single time, that's what halo is. Same guns, same concept, same recycled everything. I know If it isn't broke, don't fix it, but nobody ever talks about halo doing the same thing it does in every other halo game . Halo 5 has a few new things(which I personally approve of). Also, I really dislike the community. Most of them worship halo like it's their God, and talk shiit to any other game, or anyone who doesn't like halo.
