Xbox brought the backlash on themselves. The way they handled the XB1's launch caused millions to jump ship to the PS4.
However, Halo 5 was a great game. Sure, the campaign was lacking, but the multiplayer was the series' best. Gears 4 was good, much better than Judgment, and Gears 5 is quite possibly the best entry in the series there too. Sure, they may not be as groundbreaking as they were years ago, but they're still incredible games.
I adore Nintendo, but... For almost thirty years, they stuck to the same blueprint with Zelda and Mario. Pokemon hasn't changed since the 90s as well. Why do those titles get a pass, but others get overly nit-picked?
Don Mattrick set the Xbox brsnd on a downward spiral. That E3 2013 will haunt them for a long time. Zelda and Mario are not a valid comparison. Breath of the Wild shook up the formula, as did Mario Odyssey. Critically speaking they are amongst the 10 greatest games ever made.
Microsoft hasn't been as lucky with their IPs. Halo stopped being a great game since Halo Reach. Believe it or not great part of Halo's appeal was it's wonderful single player campaigns, it matters. Gears of War seems to have found its stride again with this last installment.
But Microsoft still lacking quality exclusives in comparison to Sony and Nintendo. Microsoft lacks an open world game that can compete with HZD and BotW for example. They have Fable but they haven't touched that franchise on this gen. Last Year Sony Had God of War, Microsoft has nothing to compete with that, or with the upcoming Last of Us 2. I haven't even mentioned Death Stranding, and the FF7 Remake. Microsoft lost a lot of ground this gen, they better come out with some new IPs (That Garner critical praise) next gen right out of the gates if they want to catch up.
