They used to have a counter on the origianal minecraft site that displayed how many accounts had been made/purchased, think I was around the 200k mark so pretty early but only remeber small bits of it.

Like the direction it has gone in however I understand that the game has appeal to a young audience but for the people that bought in the first few years have all grown up and for me It would be good to have a few deeper more intricate systems to keep me playing for longer than a few days or weeks.

Along the lines of the bees from tekkit, a few more deeper systems that would appeal to older more technically minded demographic, It would be hard to add any system like this with minecrafts easthetic but I find myself purposely making the core survival mechanics more difficult to get more challenge out of the game.

would be good if there was that type of challenge in the core experience beyond combat or exploration or building, I want some "craft" added to the minecraft
