WoTC liked the TB/MP mechanics of their latest D:OS games for its similarity to PnP
Let's see: >BG series has an adapted D&D system >BG3 has an adapted D&D system How so?
Also: >BG series simulates real time combat >D&D series simulates real time combat >BG3 emulates D&D Sounds to me like the original BG series actually implemented combat as was always intended by D&D.
