So we haven't officially decided to run some old school modules, but it looks very much like that is what we will be doing for the summer.
However, I'm not sure which way to proceed. We can either jump right into the madness with GDQ1-7 Queen of the Spiders (level 8+) or start low with T1-4 The Temple of Elemental Evil (level 1+). I know at least one of the players has never played any 0th, 1st or 2nd ed. games, so low levels may be more appropriate, but then the older stuff doesn't have near the level advancement complexity of the later editions. There was a suggestion to modify whatever we decided to run to Pathfinder but I'm not sure that an update would maintain the traditional feel of these modules AND it would totally ruin the experience of seeing how things were done back in the day.
I have never run either of these modules, but I have run enough modules to be comfortable with how modules as a whole work. Since both of these are ranked very high (#1 and #4) in the greatest modules of all time list, I don't expect there to be many problems, but nothing is perfect. So those of you who have run these, any suggestions on what to look out for?
