BG3 will not ship with campaign editor. Like with D:OS2 devs expressed interest in such feature, so they might add it after launch. For now their all efforts are focused around the campaign.
What DOS2 has to do with BG3? Isnt this new series.
Such a waste, EA should bring the community and devs closer to each other. Imho, its EA's thriving force. Long 3+ year EA with community involvement should get you high sales. Ive seen quite many short EA games, like Conan Exiles, and usually they fall flat.
