The only issue I had with Rust is missing libraries.
Whenever I have to go back to Python, a language I used for over 10 years, my productivity goes down.
Rust is by far the best language I worked with and after going through the CS curriculum in uni, learning Rust taken a few hours here in there in my free time.
Guild Wars 2, evidently others do like it as the maps are usually not empty.
I would like to play a more engaging game, but I'm working too much and my brain need some chill time.
