Absolutely. So far they've only talked about the items, the open world, but hardly anything about combat mechanics, leveling up, factions you can join, online guilds, Dovahkin or whatever story elements there will be. The list of things they haven't covered is endless, and I guess at this point they just want to make the blockchain elements right. When that's all set in stone, they can fit the story and gameplay better around it. Keep in mind, the game is online in an early alpha phase at this point. They will probably use that alpha to obtain more funding to continue development on their RPG. Like you said, it's an intriguing project.
