The Power of Gameplay
Along with several other games, I am still playing Minecraft quite a bit these days. I have joined a multiplayer server that restarted recently, and have enjoyed playing Minecraft a different way. There are several "RPG" style mods currently running which enhances the gamelpay to a new level. Things, like level up skills to mine certain material, land ownership, and city warefare.
I believe the adventure update that Notch keeps talking about will have some these features, if not all of them when it releases. I do have some videos posted of some of the new cities that have just started construction.
