Well, maybe because they are an amazing studio that makes great games with little money. They have in my opinion the best track record of the decade, only rivaled by Fromsoft: New Vegas, PoE1, PoE2, Stick of Truth and Tyranny. Even Outer Worlds has great reception even though it sucks. Larian has one great game in the decade with DOS2 (DOS1 sucked).
did DOS1 suck because you did not like it or you are talking in general? because it was never receive badly and got a really good score overall (from the critics and from the users)
