not at all, people just like diversity.

Titanfall, AW, Deus Ex human revolution, Blops3, etc are all (fairly) recent. It doesnt bring much of a gameplay change, and very little setting change.

What better to have a futuristic game followed by, for example, something in vietnam or WW2? The gameplay would be diffrent, and it would make the next future game seem like a new experience again.
