potions and enchantment =/= rpg
How does a mostly singleplayer game become an RPG anyways?
And if you don't like it, it's not like you HAVE to enchant stuff or HAVE to make potions.
You can even disable structures in NPC villages and strongholds somehow make it seem more like an RPG.
The only gameplay-altering new thing that is not optional is the hunger bar. Everything else is completely optional.
