Good sales means more RPG fodder in the future and maybe a D:OS3.
I applaud all of that. I'm glad I bought the game in EA, it's already a ton of fun (got > 100 hours on Steam), I will closely follow the development process in the future, it made me buy dice even (Amazon told me they will be here tomorrow) and it even made consider starting tabletop D&D.
So... I'm happy with Larian, with BG3, with D:OS2 and I hope this will help giving birth to a new era of RPGs on computers, one, where this genre I love so much (since days of Ultima VI actually, yes, I'm THAT old) will be seen by more gamers as something they can really enjoy.
