Keep on the Shadowfell
This was the introductory module for 4th edition in 2008. It gets a lot of flak for being a grindy combat based adventure, and it is, but all of 4e was based on that assumption. I thought it was quite fun, but I did take time to flesh it out and expand far more on the roleplaying aspects, and to make the plot a little more interesting.
