I wouldn't say "spectacularly", as I don't remember that many attempts at true end-user apps. Enterprise is ripe with Swing. Nowadays of course the web has blunted our pain receptors for memory bloat and non-native UIs, thus you're probably running three Electron apps right now, compared to which Java is Win32ASM. And as others pointed out, for games it doesn't matter anyway. You're not building a AAA-game or something for a 6510, so GC pauses and memory consumption don't matter, either. Plus rapid-development, refactoring and a setup where OOP actually makes good sense. I wouldn't start Kotlin for that, but if you already know it, there's no reason not to use it.
