Level cap of 10 is In line with most D&D adventure modules, Decent into Avernus is 1-13
The only published adventure I’ve ever done that’s spanned 1 -20 was the temple of elemental evil
I have 800+ hours into BG1 on steam and only half the achievements no idea how many hours I would have put into it when I was swapping discs
BG2 is much the same 950+ closer to 75% on achievements
