The most recent Hitman games are best in class. Three games worth of levels, rogue-like mode to string them together randomly with random objectives if doing the story again isn't your thing.
I'm excited to see what IO does with the James Bond franchise too. Even if it's just a reskinned Hitman, it'd be worth it.
This is a weird take. Rust is very popular and is the current heir apparent to C for systems level stuff. It's a great choice to start a new DE/toolkit.
As for the rest, you're right the end user doesn't care about the language their graphical app is in, but the developers fielding their bug reports and making fixes/features sure do.
