League definitely works, I am playing it on my main PC (running Arch) and on my Steam Deck.
There have been quite a few upgrades to the Wine version and the script, you should now be able to get it running just fine using the standard Lutris script with maybe some additional steps from /r/leagueoflinux wiki (can’t remember exactly anymore, been a while since I installed it)
Of course, still expect standard League client bugs, but other than that it works perfectly!
And Skyrim took 6 years to make for a 100 people working a full time job?
How long did you expect 77 people working in their spare time to take? 2 months?
