Albion/YMMV


 * Anticlimax Boss -
 * Disappointing Last Level - Of all the islands, Nakiridani is probably the most entertaining, giving us a higly interactive environment, plenty of opportunities to learn about the people's culture, not to mention an original plot, and original setting. Later islands were much larger, had more generic settings, less interesting quests, and never really encouraged too much interaction with the people. By the time the player nears the end, the whole thing comes down to endless repetitive fights in Khamulon, and long, boring puzzles that do nothing beyond challenging the player's patience, in Umajo Kenta.
 * Game Breaker - Sira can paralyze any single enemy in the game with her Thorn Snare spell, including the final boss, making boss battles ridiculously easy. Her Frost Avalanche spell does this to every enemy on the battlefield (except bosses), reducing most battles to tedious rounds of ice breaking.
 * Sira is practically a walking Game Breaker -- in addition to the above, she's actually almost as strong as Drirr, is one of the best ranged attackers, and her "Fungification" spell is by far the strongest single-target attack spell, more than thrice as powerful as Lightning Strike! (Its only disadvantage is that if it strikes the killing blow, the monster doesn't drop anything)
 * One of the late-game dungeons sports a trap that summons a horde of powerful demons to attack you. Normally, this is lethal to the party, but Mellthas' Demon Exodus spell, once properly leveled, can vaporize the entire horde in a single round. As the trap will faithfully conjure a demon horde every time you step on it, this process can be repeated indefinitely for massive experience.
 * Goddess' Wrath, once you power it to full. Can you say, "guaranteed instant death for all enemies"? Only downside is that it prevents you from looting their corpses, but you can only really use it for the final dungeon, so it doesn't really matter by that point.
 * Good Bad Bugs - The Iskai healer in Jirinaar may randomly give you a healing potion as you end the conversation with her. The bug? You can do it as much as you want, making both a big reserve of free potions and a lot of money by selling more of them.
 * Another bug allows you to sneak into Kenget Kamulos dungeon without Khunag, but you'll need this only if you want Siobhan in your party really bad.
 * Most Annoying Sound - The bleeps coming from the internal speaker almost every time a bug is encountered. It's even more annoying when the bug is fatal (the game crashes and all unsaved progress is lost).
 * Nightmare Fuel - Dungeons. Just imagine those dark and clearly alien hallways with the sounds of water dripping, chains ringing, heavy doors opening and closing, animals howling, combined with eerie music and monsters growling and jumping out from behind the corners or just standing motionlessly and waiting for you to approach, not to mention the occasional magical or alien phenomena or complex mechanisms you come across every now and then which must all be figured out while dealing with these circumstances. And let's not forget the total darkness waiting when the lights go out.
 * Nailed it. The dungeons could have been the RPG equivalent of Silent Hill with a more complex sound system  It was pretty spooky as-is.
 * Scrappy Level - . It is extremely long and full of repetitive encounters combined with empty rooms. It nearly drove the author of the aforementioned Let's Play mad.
 * Other players find that one of the best dungeons for its lenght, sense of danger (you cannot just escape from it and return later), complexity and some ingenious traps, and would rather point their finger at the caves - the engine is really bad at rendering "natural" dungeons and navigating them is very frustrating.
 * Special Effect Failure: Some scripted events will use special animations (like characters trowing objects or firing weapons, or more commonly, explosions) which are actually animated screens, imposed over the main window. They cover up interface objects like the clock or the monster eye, and are not always aligned with the background. In the above mentioned cutscene with the fireball, Tom's entire front may disappear until the impact.
 * Viewer Gender Confusion - Drirr has been mistaken as female occasionally. Given that he's an anthropomorphic cat-thing, though...
