It's actually pretty hard. I'm not saying this in a "it can't be done" way, but if you claim we can't compare them with Nintendo, then we can't compare them with Microsoft either. Microsoft's biggest advantage going into gaming is that they are first and foremost a multinational software company that is not only fully aware of all international markets and needs, but they also have very strong infrastructural to implement strong standards across all markets based on their experience and existing support in all these regions.
Sony is a fragmented company with interests in hardware electronics, gaming software and hardware, the film industry, etc. It might seem like they have a strong presence all over the world, but their actual business infrastructure doesn't remotely give them the advantage Microsoft has. It's unfortunate, but that's how it is. It doesn't help that the way Sony's leadership and business culture works, the Asian region is under the purview of Japanese business management rather than a local head office for the region which is better positioned to make big decisions.
It's not "hard" for Nintendo to give a shit about more regions and take an active stance in attracting as large an international audience as possible either. They just have to do it. They don't do it because it doesn't seem to be something they are aware of or interested in. In the same way, the sort of company Sony is holds them back. What is easy for Microsoft is hard for everyone else, because you don't build this sort of international business overnight. Microsoft was way ahead of everyone's game in this regard before they even stepped into gaming.
You can argue that Microsoft being a software company was always better positioned to pull off a global digital platform better than Sony. But Microsoft had virtually zero hardware and retail presence in Singapore when they launched OG Xbox and yet they managed to pull it off well. Sony already had significant existing consumer electronics businesses here way before the PS1 and PS2 days with a sizable retail presence. Sony TVs or Walkmans all had English manuals and packaging and user interfaces because they know no one outside of Japan understands their language. It was pure laziness and incompetence from them when it came to the PS1 and PS2. That's why the company doesn't make money on the whole. It's a stupidly inefficient and poorly managed company.
Of course, all of that isn't really surprising since it's coming from the company that appointed Kaz fucking Hirai to the CEO position.
Microsoft is hardly a well-managed company either but it really isn't rocket science in this day and age to create and manage a global marketing and distribution platform. Look at where Steam is and look at how much resources they started out with.
