Path of Exile has a very similar same thing. It has a "map system" where a map item opens a new small dungeon for you to explore. You can also apply currencies to modify the map item to make it harder, but drop more/better loot. The difference is that all of them cannot be purchased as MTX and you'll have to get them as drops or trade with other players.
This is just a greedy way by having a chance to fail when it comes to converting real cash to in-game credit. :/
