nix allows for flakes which are 100% reproducible (ie. you copy paste a flake it would do the intended stuff only) , this make me realize that now we can have flakes for games like do you want inscryption , sure add this flake and this would install all dependencies and lutris etc. and you just have to link us to the gog-games.to / fitgirl-repack / dodi-repack variant (preferrably , gog-games.to since you can verify it with gog) (i have picked only the goat of gaming piracy from megathread) , imo this can give huge boost to gaming in linux and wine is literally really close to giving native performance and you wont even see the difference
the same logic can be applied to ms excel , powerpoint etc. but i dont see the point after using libreoffice (literally the best thing ever)
We are not in want of such solutions, Lutris and other existing solutions are capable of making game-specific environments already. The main problem is having enough volunteers to painstakingly run, test and submit the exact dependency parameters for each game that makes it run correctly. Same will be the issue even if we shift to Nix or anything else. The problem is manpower scarcity, not lack of tech.
