Star Rail is surprisingly fun, actually. I was very wary given that it's a gacha game but it's pretty generous with the freebies and if you have the self restraint to just make do with the characters you obtain normally then you don't need to spend anything at all.

Extra points for the game's first world being inspired by Russia! That was a pleasant surprise. It's a shame FFXIV decided to tie Russian elements to Garlemald and then did away with the place in its entirety. There's so much missed potential there. Just imagine an entire expansion delving deeper into the Russian and Roman influences? I'd certainly find that to be quite engaging.
