GamesIndustry.biz said:A marketplace on its own may create the potential for an interesting in-game economy, but it sounds as though Artifact all but requires a constant cash flow from its participants. At launch, there is no way to earn packs through play, and in fact there is no single-player campaign, ranking system, or really anything to Artifact other than playing the game with someone else for fun. Barnett clarified that these features may come later depending on what the community wants, but for now the team was only focused on releasing the core of Artifiact - something he'd repeat multiple times throughout our interview, including when asked about cross-platform play with the game's mobile version.
Monetization is not the only place where Valve is trying a somewhat-unconventional spin on card game norms. The game will also feature live chat that allows players to communicate with one another during a match - even strangers. I asked how that chat and the community in general would be moderated to discourage bad behavior, but neither Barnett nor Garfield could offer any specific idea of tools that would help someone avoid a random internet stranger hurling insults at them during an Artifact match. At least at this point in development, it seems as though Valve is leaning on the hope that the community might simply not be a problem.

"When it's a one-on-one game, what is my motivation for saying something awful? But when you're in a game with a bunch of other people and you say something, a bunch of other people laugh at you, so something happened. We tend to see people behave very differently in one-on-one situations."
