Gameplay, Teyvat, characters, music, puzzles, etc. except pvp. You can find all of them in the game. No other games can compare (unique/no competitors). The only thing that I don't like is FARMING ARTIFACTS for my characters. Getting a good artifact set for one character is like finding a needle in the pacific ocean😅. Just for one character, you need 2-3 MONTHS worth of resin. But who wants to farm artifacts for that long? Edit: I think the real problem here is the resin shortage...
