I didn't say that was the case; if anything, Larian has found its niche by specifically not being mass-market.
I'm not sure I'd completely agree. I'd ascribe the success of Original Sin to it opening the cRPG genre to the wider audience (so "deniche-ing", if you will). Compared to other cRPGs, OS games are very modern-audience-friendly and casual-friendly. Of course, it's still not "tens of millions of copies sold blockbuster", but the games aren't "cult classics".
(To be clear though; I do not perceive Larian as a bunch of soulless suits. They seem very passionate about their games and all the interviews were great to watch.)
