Quality, not quantity.

I cant speak to the qualiry of starfield, but i do t think the teo games should be compared.

Bg3 is extremely story driven and incredibly immersive with detailed and intricate combatz catering to many different playstyles in an almost sandbox format.

Starfield is a vast exploration and semi combat focused rpg. Relying more on managment of inventory, crafting and development of kit.

Personally its not my style, skyrim was great but i always got bored way before completing it so i dont think im gonna enjoy starfield.
