I had a laugh when I saw Larian's post, which I don't think came off as shaming in the slightest. The dev team always seems to have a good sense of humor. What on earth.
It does open a fascinating different discussion about how people approach RPGS, though:
I can understand that the sheer amount of customization options can be overwhelming, so if you just want to jump into the game you might just pick something that feels safe and familiar. Also, a lot of people do just seem to want to play themselves in an RPG, with varying degrees with much they insert themselves and their own choices into that world. (I always think of The Witcher 3, with some players saying they wouldn't want Geralt with Yennefer because they wouldn't want to be in a relationship with her in real life. There's a lot to unpack there -- also how bold to assume Yennefer would be interested. lol.)
For my part, I love making unique characters for RPGs. It's fun coming up with a bit of a backstory, and then making the choices throughout the game that feel in line with the character you created, as opposed to what you would do in that situation. I spent months planning out my Inquisitors for DA:I! The only exceptions with not experimenting with the character creator are when the default character design is much better than anything you can make, like the Mass Effect Trilogy or Dragon Age 2.
...It's good that BG3 is in Early Access, as I might need a few years to decide on a player character. The amount of customization options are insane.
