@iska oh okay I'll answer earnestly then:

generally garbage collection is unwanted in game development so that's a non-starter for most people which is why it's not there

the main thrust of the language is supposed to be about reducing friction for the specific things gamedevs care about. Just talking about the bigger things, there's SOA/AOS conversion without changing up structure definition, good reflection and metaprogramming features (intercepting and responding to compiler signals is neat), strong but optionally automatic typing, project/build management built into the language itself, etc

also don't bother wih the continuations post i mentioned it was bait but no one got got by it
