You forgot to mention they sold 30% stake of the company to the world‘s largest game conglomerate Tencent. They‘re also working on a supposedly much larger game than BG3 now and plan to release it within the next 4 years which means they will have to at least double their staff. Honestly, judging a developer entirely by a recent success isn‘t a good practice even when it‘s as massive as BG3. Most people who talk about Larian have a very warped impression, even when their games are great so far.
