Highly irrelevant for the success of a game. I could list you hundred of games that did very well in sales (profit) but were terrible products.
this,
it is based on the previous IP's and brand name attached to Conan. Secondary-sector branded products from which Funcom may profit such as the Conan IP and/or other games they own, but I think the steam platform had a much bigger impact on the popularity of the game... hence why it sold so quickly. Luckily, Funcom is also getting money from the government or they'd be defunct by now.
