I'm a very experienced AD&D GM, and have run levels 1-5 in 4e: Red Box + Reavers of Harkenwold. I want to start a new mixed-experience group (some 4e, some 3.5/Pathfinder, and no experience at all) group through levels 1-5 in 4e so that I have a large enough pool of players I know and trust to merge the groups to continue on a shared path through paragon.
So - I'd really prefer to used prepared content for this adventure, but not run the same modules I did for the other group, given that the parties will be mixing afterward and the last thing I want to hear is "Did you find the XXX? What? No? You got gipped!"
What is the best 1-5 Level adventure(s) you've run out there? I don't care if it is download, free, $$$, PDF, or purchasable online or at your FLGS. All I care about is did your group (which included newbies) have a good time and it didn't require more than an hour prep on your part per session.
*Feel free to suggest multi-module chains. I'm comfortable finding a way to glue good stuff together. Also, one of the reasons for the short prep requirements is I'm likely to build paper terrain for this adventure, so something with interesting visual elements is a big plus.
What is the best first adventure to run in D&D 4e? does not contain an answer to this question.
