Writing and story is not a strength of Larian. So much stuff in DOS2 does not even make sense, let alone it is a sequel of DOS1 and nothing they tried to bridge together from the first game makes sense at all.
Just because they forced Braccus Rex into the game in a role that made no sense at all and mentioned Sourcerers does not make it a sequel. Not only that, but the writing within just DOS2 was messy.
The last 3rd of the game was rushed and filled with incomplete story and so much excess fluff, despite also being undercooked. I have no idea why anyone would think Larian has good writing.
All true, and I talked about here non stop on the early days of the EA. But the old excuses of "we are small indie studio" don't work anymore... If they knew it's a weakness they should have addressed it once they had the budget.
