New World Computing - destroyed by idiotic publisher practices (3DO).Witcher 3 made money because of graphix and bewbs, if it was a real rpg, CDProjeckt would be in the company of New World Computing, Sir Tech, Black Isle, Troika and Origins.CD Projekt RED has singlehandedly brought back the RPG Reinassance, and made money because of it. The Witcher 3 is probably really fun to boot, which is more than I can say about the other roleplaying videogames from the reinassance.
Black Isle - destroyed by idiotic publisher practices (Interplay).
Troika - overemphasis on game design at detriment of everything else resulted in three conceptually brilliant but otherwise deeply flawed games that scared away majority of potential customers due to being barely playable out of the box. Aka idiotic developer practices.
Origin - sold themselves to EA, released Ultima IX and WC Prophecy. Nuff said.
Why did Sir-tech go bankrupt?
So far, CDProjekt is a relatively young and successful CRPG developer (Witcher came out in 2007) in its prime. So far they haven't made any retarded mistakes that would allow you to put them into the same category as the aforementioned have-beens.
