After playing The Division it's hard to go back to Gears' rough gameplay, and as more and more games offer smooth, seamless animations and transitions the more and more outdated Gears are becoming. The gameplay that started the entire series and changed the entire industry is becoming its biggest issue IMO, it's simply not that fun to play anymore, and is a big limiting factor.
And the plot/universe isn't helping the series at all, I feel it's like with most soap operas that should've ended after 1st season, but instead are being prolonged with another 4, 5, 6 completely forced seasons just to milk every last penny from the audience. I think many will agree that Gears should've ended after a trilogy, where humanity finally wins the war, Locust are completely wiped out, and things are slowly coming back to normal. But instead I really don't fell any need to keep playing the series, enough is enough, what they are trying to achieve, what are they trying to tell? At this point I think it would be just better to make Gears 6 where you play as the bad guys, destroy the humanity, and end the series once and for all, and let The Coalition start a new AAA IP.
