In the past, I've used MORT to play some Japanese MMO game. In-place overlay makes it easier to actually play the game instead of doing dictionary lookup on the side.
These days I stopped using realtime translator and just embrace the slow pace of learning these languages while enjoying the game story.
MacOS however truly takes the cake. An OS that’s great for creative softwate, working with images, video, audio and so on, and every single music player is something designed by aliens and/or buggy and/or missing some basic features. I went through ~five different players just to find one that has a waveform seekbar, eventually finding it in quodlibet, which while somewhat functional fits in the designed by aliens part. Baffling.
Technically fooyin also builds on macOS, but it's not officially supported yet, there's some works here[1] and there[2].
