Phisto Roboto said: I would suggest the Keep on the Shadowfell for someone starting off their DMing experience in 4th edition. It has all the necessary tools and resources within the module it self. It also has enough options for the players to explore a bit and the ability for the DM to add their own elements. If you do this, search very, very heavily for the any errata, or online fixes for Keep. As written, it doesn't work for new players, and certainly not for new GMs. It will teach you very bad habits, and create confusing situations that will just make your players feel that the game is too easy, or that you're blatantly trying to kill them. Make sure you use Monster Vault, or MM3 updated versions of creatures in this module, not as written. It's the very first 4e module, and numbers suffer for it. There is an early trap in Keep that doesn't work, for example, either it doesn't trigger properly (not catching anyone in it until the second activation), or it's impossible to deactivate, as the mechanisms for the trap is located inside, with the player currently dying. The entire module is full of stuff like this.
