I wanted to try out Erlang + Elixir since forever, do you think Phoenix LiveView would be a good starting point? For example, to create something like a simple game with modest persistence and only very limited RT-features? I was thinking about sth like a quiz app, not a web MMORPG of course :)
Or is LiveView only useful to optimize partial page reloads and SEO?
LiveView is perfect for that. one of the easiest to understand demos of it is actually something just like that.
that said liveview is capable of 60fps server-rendered animation, so it's definitely not just for speeding up page loads.
