Better visuals and much faster/cheaper for the developer to make.
We are still in the infancy of the technology and the vast majority of games with ray tracing doesn’t fully utilise it as they must compromise to support normal raster, leading to half baked implementations on engines not designed with ray tracing in mind.
Ownership in terms distribution of digital software is a bit funky I guess, but from a consumers point of view, there’s really nothing GOG/game companies can do once you got the installer. You’re effectively owning the bits on your hard drive and there’s nothing they can do to control what you do with those bits. I guess from a lawyers perspective it may be different, but in practice there isn’t much.
I’m not sure what you’re getting at with the licenses though? A game licensed under MIT would be free to share, attribution shouldn’t be much of problem.
Put the installer on a USB stick and sell it.* I assume you’ve never gone back to the electronics store where you bought your dishwasher and expected to sell your used dishwasher there.
Pathfinder also has fairly detailed difficulty settings panel, you can tailor the difficulty to your liking. Story mode difficulty and auto level up presets makes the game beatable for even your grandma, so you can ease into the system.
There are also some great guides out there for different builds for both companions and main character.
I can’t remember ever having used meta critic to guide a purchase. There is so much content both from forums and YouTube/Twitch that gives you much more accurate impressions of games. Meta critic seems rather pointless nowadays.
