This game is the reason why a guy [the legendary u/-YoRHa2B-] started working on dxvk, to make this game compatible on linux after it released. Valve hired him and made Proton out of it. The result is the Steam Deck, this remains one of the best games for the SD.
Wow, that’s crazy (in a good way). For me, it was hard even to get really into the game. Started it 3 times from the beginning either becaused it confused me or because of relevant dxvk updates. But afterwards it really caught me until the end. Unfortunately we had to wait too long for the sequel NieR Replicant ver.1.22474487139… (lol) which is a predecessor from the PS3 area. I still have to get into Replicant now
