... it will make most other maps seem like hack work.
This is even worse. Had this with NWN modules. I guess I will play some other maps before that then.
I can recommend the following, listed in chronological order:
The Pride Trilogy (Titanic Pride, Angelic Pride and
Titanic Pride). Very good, XL maps
Goldheart. More Duncan storyfaggotry combined with excellent design.
The Lord of War. Very good and infamous battle map.
Bug Hunt. Very much content in medium map. Open, but not dynamic.
Sleeper. Very good. Lots to explore, tough enemies, semi-open but not dynamic.
Corruption. Nice storyfag map. Prose is better than that of Timothy Duncan. Somewhat confusing what you were supposed to do.
Hail to the King. Nice storyfag map. Prose is better than that of Timothy Duncan. Very linear and static.
Reavers of the North. Epic map based on Norse mythology and European middle ages.
Redbeak's Revenge. Very nice. Quite hard and "busy", maybe too much since there's not time to do side quests.
Sentinal Recognition. Fun little map, with lots of content
Shar's War. Very linear, extremely nauseating storyfaggotry, but still enjoyable. Final battle far too easy.
Unification of Rife Campaign. Very good, but third map ended abruptly and fourth map didn't end.
Amaranth Soul Shift. Very nice quest map
Fairy Tales. Very nice quest map. Very well balanced.
The Imp. Nice little quest map.
