Valve have finally admitted they messed up with Artifact and now they are working to fix the game but it will apparently take some time as the issues are deep-rooted, according to an official blog post on the Steam Community page.
Valve's Dota 2 based TCG launched in November 2018 and proceeded to be a string of disasters for the company due to several reasons. One of them is that no one really asked for a Dota 2 TCG but the reason most often quoted is that it is a pay to win game where players weren't originally offered any way to earn new cards other than paying for them.
While such a game could thrive in Korean or Chinese market, where players are not averse to buying power, it is a well-known fact that western gamers have a massive distaste for such monetisation. Star Wars Battlefront 2 was the prime example.
Anyway, Valve allegedly wasn't even aware how it would be received as they stated that "Artifact represents the largest discrepancy between [their] expectations for how one of [their] games would be received and the actual outcome". Who would have thought introducing a paid game with pay to win mechanics could backfire? Valve apparently didn't.
To give credit where it's due, the company turned out to be one of the rare ones these days that didn't just say gamers are entitled following a mess created by said company. Valve stated they don't think that players misunderstand their game or play it wrong so at least the owned up to their mistakes.
Moving on with the statement, Valve said that they became aware their original strategy of releasing new features and cards wouldn't be enough to fix the deep-rooted issues with the game.
Just like with the case of Battlefront 2, one of the most egregious mistakes is the monetisation model and it looks like Valve might just give Artifact better monetisation as decisions regarding the game's economy are among the ones that will be re-examined.
