Scrolls, the upcoming game from Mojang and followup to their extremely popular Minecraft, will contain certain aspects commonly found in free-to-play games, but will still require you to buy the game initially.
Markus “Notch” Persson explained the concept to Gamasutra, “It will have an initial cost that gets you started with the game. The game will be designed so you can in theory play the game with just this initial cost, but if you want to you can buy more scrolls to play with.”
In a blog post, Notch is critical of the usual free-to-play model, saying, “people who think ‘free-to-play’ is a great future are mostly game developers, not game players.” To make the system more enticing, micro-transactions won’t be the only way to obtain new scrolls. Notch goes on to say that the initial expenditure to get into the game will also grant you regular updates with new scrolls, and participating in ranked tournaments can also net you scrolls, all without spending anything extra.
