Sending this to Phil Spencer.

Generally speaking most games go unnoticed compared to CoD, Halo, Mario, etc.

A lot of the X1 games I own are million sellers or may get there in time. Not every game is gonna be a hit, that happens on every console.

Nintendo doesen't have a marketing problem. Nintendo's problem is the Wii U has a lame gimmick, its expensive, and its library basically just appeals to Nintendo fans. The Wii U is a disaster, marketing isnt the issue.

I'd keep pumping out Halo, Forza and Gears every year until I'd destroyed the franchises completely and interest in the Xbox brand waned. As this was happening, I'd be testing the waters with my favorite pornstars, to see who I'd like to travel with the most. To Oslo. Helsinki. Various tropical destinations. After I'd decided on my favorite hooker, I'd head back to the U.S. for a meeting with Big Deez Productions to secure exclusive rights to Shaq Fu: A Legend Reborn, and smoke some ecstasy pills with my stepson Kaleb.

Really focus on Asian and European markets

Lots of great ideas here.

I'd just tweak a few things really, Phil has done a great job with what he has and should keep doing it.

Try and reduce costs, and improve revenue, so MS management don't sell the division off.

Make better decisions on which 3rd party games to partner with. This is an area where PS4 and Sony have been much better this generation.

2nd party will help fill out your software until your new studios get going. I'd say at least 2 are needed. Lionhead needs shaking up. Buying remedy would be a good fit, but they will need improving.

I'd get Oculus onto X1 to avoid being left behind if virtual reality takes off massively.

Give Rare and its franchises back to Nintendo as a gift

I'd make sure to buy COD out of the sony contract (yes, it sounds greedy, but it drives sales). I'd make sure to also grab Mass Effect for 2016 (for the RPG gamers) as well as several other third parties. I'd also end the Halo franchise with Halo 6, and Gears at 4 or 5. I'd also make sure to get a slim-xbox ASAP, and cut the price to 299. I'd focus on marketing this device as a gamer platform, and try to earn people's trust back. I'd continue to add more title's for the backwards compatibilty list, and convince a few other third parties to join in (rockstar for example).

Too lazy to say everything here, but I'd definently stick to alot of what phil was doing, but also branch out a bit more.

Markting was definitely one of the issues. Nintendo did a very poor job advertising the Wii U during its launch. Wii U isn't perfect, but it's far from being a disaster.  

I honestly believe the Wii U's marketing was fine.

But the name of the console confused consumers and its too expensive because of the tablet control. It it stuck with the Wiimote it would have been more successful.

Wii U is a sales disaster because of price, marketing cant help that.

Technically, they're both aspects of the overall marketing plan.

OT:

I would effectively convert the next Xbox into a 'PC for TV box' (a bit like Steam machine but with lots of actual PC game support). Have a functional Windows Lite on the machine but make it so that PC games can be played (a lot of PC games already support the 360 contoller so it wouldn't take much to add in controller support for the new console). These can then be sold on Live Store at launch so it already supports a massive library of PC games for download. It would effectively have the largest games library of any console at launch. 

I would then add in mod support a bit like Steam workshop with the ability to install mod tools for different games (with keyboard and mouse support for those who are serious).

I would also get into bed with Oculus and Facebook more with full VR support.
