So what kinds of examples did BG1 and 2 stay more to DnD rules, than that of BG3? I've played DOS2 and BG3 is vastly different. Idk how people are saying there are similarities of the 2 games. I've never played DnD but after having read many guides and rulesets of DnD 5e to better learn how to play BG3. I feel like they got it pretty reflected. Granted some mechanics must be WIP because it feels pretty exploitable, ie the jumping and long rest mechanics.

So again the question, what about BG1 and 2 stayed more to DnD than how BG3 is handling?
