I'm trying to prepare for a low-prep-time starting game for D&D 4e. The obvious solution would be to buy a prepackaged adventure for 4e for 1st level characters. However, from what I can see, only one (H1, "Keep on the Shadowfell") was produced to prepare characters for the sequence (H1-H2-H3-P1-etc) and it's out of print.
That seems a bit weird to me, so I'm wondering if I'm missing something. Is there a replacement starting adventure for this that would prepare characters correctly for the next adventure, H2? Should I go with HS1...but then how would I get from there to H2 (There seems to be a large level gap)? Is there another prepackaged option out there, possibly from another company?
