I live on a fault line along the pacific ring of fire, and so building with wood was an absolute necessity for us so long, as they were structurally more lenient to the constant earthquakes. Even now I believe our old government building is the largest wooden building in the Southern hemisphere (and it’s only 4 stories tall). These days as construction techniques have changed, we’ve obviously built things with concrete, steel, brick, etc., but the wooden tradition remains strong, with a huge majority of modern houses here still being built like this.
That aside, wood was also just a much cheaper material to build with, so it was the most economical material to use for a long time for much of the “new world”.
He’s not talking about Larian, he’s talking aboutbthe actual D&D team at Hasbro and Wizards of the Coast. Hasbro got a new CEO last year and the way they’ve been operating certain business units like WotC has changed dramatically, coupled with massive layoffs across many Hasbro subsidiaries. All he’s saying is the DnD team at WotC now is completely different to the one that Larian knew as they developed BG3.
