Meh…I find MMO’s boring. Quantity over quality, and always full of microtrans trash. I doubt there will be any real influence of those shopping mall games on good rpgs. At least I hope not.
How BG3’s popularity will influence rpgs in the future? I imagine a move from text based to more cinematic as number one, and a continual shafting of solid single player mechanics for multiplayer elements as number two. However…it all depends on how much it actually sells.
