you can see there are several factions all trying to achieve a goal. and the goal is a BBEGal unto herself.
who can free her or keep her locked up or banish her or reap the rewards from selling to other sides or...
plenty, plenty of opportunities.
still i hate T1-4. it is by far the worst module TSR put out for 1edADnD. not the worst product from the day. The Shady Dragon Inn still holds that honor.
edit: the problem with T1-4 is the options. too many open ended ones. which don't play a part in the goal. meaning for the PCs to complete they need to have a strong focus from start to finish.
I am currently running ToEE for 2nd edition and am loving the flexibility within the module to tailor it as I wish. I hate being railroaded as a player and hate doing the same to my players; although we all know there is a certain amount of it in the game.
I am particularly enjoying EGG's unique descriptions and chapter introductions in the module; he lays out the adventure and let's it unravel as dictated by the players moves. As a DM, that's a challenge for me and keeps my players on their toes.
AP's in general are exciting because there is so much gaming information to either use directly or mine for your own game. What deters me from starting one is expense and the time it would take to complete it (I don't have a f2f group; all of my gaming is online these days).
