On: “What if it changes?”

[magpi3]

Minecraft is written in Java.

[astrange → magpi3]

It relies on native libraries like libjwgl so it does still have portability issues.

And most game consoles can’t run Java so they had to totally rewrite it there.

[mcosta → astrange]

Most game consoles are amd64 or ARM. Running java there is trivial.

[astrange → mcosta]

Minecraft for 3DS, Xbox 360, etc already exists and is a rewrite in C++. It’s older than current game consoles.

But they don’t have JREs even if they have the right kind of CPU in them.
