After a careful consideration of the pros and cons of various business models, including those of Crowfall, Guild Wars 2 and ArcheAge, the Das Tal team says that it is leaning toward a buy-to-play model with a cosmetic cash shop. One additional revenue path that the studio is considering is to allow players to pay to launch specific ruleset servers.
“Buy once is still the standard for almost all single player games, as there is rarely any substantial development of the game after release,” the team posted. “It has also become apparent that a buy-once model can be utilised by games with ongoing development by meshing together different aspects of other payment models.”
Whatever the team ends up deciding for its revenue plan, it doesn’t want to hurt the game because of it: “We don’t want to compromise the quality of the game, or our community’s enjoyment of it, because of the model we choose.”[Source: Dev blog]
