It seems the lessons they learnt are;
Console bussiness isnt worth the effort, so keep the franchises that make lots of money (halo,gears,forza) and slowly try to move everything to the windows store, and get the console gamers there too (steam is very profitable, MS wants to be that).
Multiplayer and games as services, make money for along time, and you can have micro transactions help you turn profits, so everything should just go that way, I mean it only makes sense from a bussiness perspective right? So all games from now on they make, will be like that.
Maybe Im just being a negative nancy, but it really seems that way to me.
Welllll, MS has always been a game dev/publisher, and they decided to enter the console market because they thought that consoles were going to kill the PC. Instead, Mobile took a far bigger chunk out of the PC market, which completely negated MS' original plan (which was to take down Sony, and thereby push users back to PC). History will tell us that what actually happened was that mobile hurt PC MORE than Sony, and Steam was actually the one that began revitalizing PCs.
Meanwhile, MS went deep into the red on xbox, and took all their own games off PC. Now they're trying to go back to PC, but everyone in the PC market is now trying to market windows alternatives....which is what got MS worried about their future in the first place. MS was never about the console market, they were trying to prevent the softening of Windows sales.
MS have enemies on all sides now and garnered themselves a pretty bad image in the process.
What MS needs to do is work on windows. Make deals where they can, sell their games and apps, and focus on profits. Instead of making windows an obvious choice, they're putting a leash around their customers and telling them they have to do what they say, or they don't get new content. The mainstream simply doesn't respond well to that kind of control (unless it's apple).
