Yeah, too many little details to remember in the manual option.

That said, it's worth it to learn how to do it by hand if only for the handful of games that won't just run when launched from a Launcher like Lutris and you have to manually read the logs and then tweak the config or just because there some interesting advanced features in the various adaptor layers we're using that aren't mapped to config options in the Launcher - for example, just yesterday I discovered how to get DXVK - the layer than translates DirectX calls to Vulkan calls - to overlay various pieces of useful or interesting information such as FPS and CPU load on screen (in what's called the DXVK Hud) on the game during play and because I understood how it was launching Windows games a while ago I figured out how to get Lutris to default to launch games inside a firejail sandbox which disables networking and blocks system level access.
