Minecraft Dungeons could've easily succeeded if they allowed players to create and make their own dungeons, Campaigns, massive boss battles, and Raids, along with free DLC and Mod support and development tools. instead Mojang fell into the cycle of Cooperate greed and locked the game down so only they can create content for it, and charge even more money for it.
Minecraft Dungeons is the definition of abandoned potential. That game was infinitely updateable and is AMAZING. I would buy every expansion dlc that ever dropped if they kept going. (That isnt seasons)
