You can’t compare the Xbone mistakes and their damage to the PS3 mistakes and their damage. For starters, the Xbone mistakes were gargantuan in comparison. There are still people who believe the Xbone cannot play games without an Internet connection. That it still requires you to hook a camera up to monitor you before you can use it.
Second, virtually any mistake you can conjure for PS3, the Xbone also had it. It was too expensive. It wasn’t a tough console to make games on like PS3 but it was weaker which lead to the same results, weaker multi platform games.
Lastly even with the mistakes, PS3 was on pace to outsell the 360 from day one. Meaning Sony had a reliable fanbase and following to rely on for recovery. MS doesn’t have that luxury. They fucked things up right as Sony was doing everything right and have done everything right all gen. Even during the 360 gen MS dropped the ball the last chunk of it going all out Kinect.
The situations aren’t comparable at all and sales show that. As for exclusives of course Pugs is right. They’re important for console health and sales but they aren’t the most important factor by far unless you’re Nintendo and don’t get much third party support. Price and word of mouth are much more important. As sales show, most people this gen didn’t buy a PS4 for Uncharted 4 or GT7, they bought it because their friend plays Madden and CoD on it and they want to play together.
