to be fair Minecraft was ported to C++ for anything but PC, and IIRC as of last year the PC version was ported as well, the only thing standing in the way being mod support. The reason Notch wrote it in Java was because that's what he knew, not exactly because it was a fantastic choice for a 3d game.

Bedrock edition is available basically everywhere and unified the non-Java platforms, yeah, though the Java edition still gets feature updates in tandem. There are still other differences between the two that will likely never be rectified (not least of which are bugs becoming relied-upon features). But all that's kind of beside the point. Clearly Java wasn't a bad choice.

As proven by his bank account, being written in Java wasn't a blocker for commercial success.
