I played Artifact, it was fun until it died, but a very tough set of lessons for Valve to swallow: 1) Their reputation really has been damaged over no HL3/Dota 2 money grabs. 2) That they can't just publish anything onto Steam anymore with little to no upfront communication. 3) Not all monetisation models are viable - especially with the recent loot-box fiascos. If they wanted a card economy the game should've been free with random cards, with the option to purchase cards to have your own collection. The past few months they've definitely started to change over the response to Artifact. Dota Underlords was shipped in only 5 months, so it just shows what they're capable of with a little pressure.
