“I cannot play two games that are completely different from one another because one of them came out a month earlier” -Every human being ever who could only enjoy one thing
It is odd, but I suspect it shifts peoples expectations slightly even if they don't think about it. Also people might not be willing to spend $60 two months in a row so Baldur's Gate could be dipping into some of Starfields potential earnings here.
BG3 is. It will be better than Starfield if you like to be treated like an adult. Starfield will be better if you want them to hold your hand but make sure you don't do anything "wrong" that could "hurt your experience."
As someone who enjoys RPGs, knowing I will have BG3 on my ps5 (let alone a significant backlog) makes me care less for missing out on starfield. Totally different games, but with huge RPGs and little play time, any such game can literally take up months of my gaming life. I suspect I will eventually want to play starfield, but I won’t be in a hurrry.
