Depends but likely difficult (Gaming)

This is true. There are also two trends that has made this less of an issue over time.

One is that hardware has become more similar--like the change from PS3's RISC architecture to PS4's x86-64 architecture, which both Xbox and PCs use. Apple has used x86 for a while but I believe they recently announced a change in architecture (not sure of the details on that).

At the same time, there have been multiple software development kits with an eye towards multiplatform support. (Monogame is one such example.).

That being said, sometimes there are just weird quirks, like how during OG Destiny development the PS4 consistently had frame hiccups when playing video like the intro cinematic which none of the other platforms had.

None of this is to negate that multi-platform development is harder than single platform; it just happens to be less hard now than it was in the past.
