Is Minecraft Dungeons more worthwhile for Xbox One or the Switch, and more worthwhile for the normal or the Heroes Edition?
Whether you buy Minecraft dungeons for the Switch or for the Xbox is entirely up to you and depends on which console you prefer to play on… Personally, I would actually tend to Xbox in terms of taste if I had one.
Buyers of the Hero Edition get the next 2 expansions free, additional skins, a pet (chicken) and a cape included.
However, I recommend that you look at the gameplay and the scope of the game before buying.
I personally didn't do that and expected a mix of Diablo (III) and Minecraft and was a little disappointed by a list of missing features. Despite everything, it's a fun, entry-level game.
