Of curse there is a lot of great Management and skill in Larian and they worked Hard to reach the Level of skill they have Shown of. However there are also certain eternal Faktors. AFAIK there have been several Times in the past where the Studio have easily gone bankrupt were it Not for certain Events. Also they have reached a critical point of exposure where enough People know them. There are several Studios which Do great games but you have never Heard of them. As an example i think Unknown Wordls (Subnautica) are creating a great game with Moonbreaker but it seems to miss the critical mass and might die during development
