Arc Fatigue: The 2002 Return to the Temple of Elemental Evil suffers from this with the Temple of All-Consumption. Divided into 300 areas across the Crater Ridge Mines, Outer Fane and Inner Fane, the module turns into a slog and can get old quickly, leading some players to protest or even quit playing altogether.
Video Game:
Cult Classic: The game still has a fairly active community of players and modders, the latter working hard to fix the Obvious Beta state of the game, add new content and modules, and improve overall performance.
Those Fire Salamander nobles are not to be underestimated. Continual uses of fireballs spells, large hits points, immunity to fire, damage reduction and very good in melee attacks.
Jackalwere will always make a beeline for your mages. With damage reduction, high attack rates and the lack of silver weapons in the game, they will easily ruin your day.
Hill Giants and Ettins ditch high damage with their clubs. While they are easily dispatch in any other games, you'll be facing them a lot at low level.
Kobolds and Goblins are annoying for the same reason as stirges, but at least you can sell their equipment for money.
Mis-blamed: The Circle of Eight mod garnered complaints from fans for including a Buster Sword. The sword model was in the core game, used by a bugged sword that can only be accessed by console.
Play the Game, Skip the Story: The game is considered to be one of the best (if not the) adaptation of Dungeons & Dragons 3.5e combat rules, with the combat receiving wide praise. On the other hand, while the story isn't bad, it is considered to be rather bland and nothing special when compared to Troika's othertwo games, which both received the exact opposite reaction.
Self-Imposed Challenge: For those who dare to try it: Ironman mode. Point-buy is disabled and you can only roll your characters once and you must accept the results no matter how bad they are. Furthermore, you can't save your game before a potentially dangerous situation like opening a dungeon door or checking for traps. If everyone die in your party, your one and only saved game is deleted for good.
Introduced with Circle of 8 mod, A cure for Amii is that ONE sidequest indeed. You need to find a swamp lotus to cure a little girl. The flower may or may show at all in a random swamp map meaning it's completely luck based. And if it's on the map, you have to fight the monsters first before looking through the scenery. And the whole thing is on a timer, meaning even if you do find the flower, it may already be too late.
