Eye of the Beholder is a trilogy (or just a pair) of RPGs developed in the early nineties, the first two by Westwood Studios that would later be known from games such as Command & Conquer, and the third one by Strategic Simulations Inc., that also published all three games.The games use a simplified version of the rules for Advanced Dungeons & Dragons 2nd edition, in the Forgotten Realms campaign setting.All games are first-person, and feature an adventure party, between four to six members, going on quests and fighting evil. The first game has them hired by the lords of Waterdeep to investigate an evil residing under the city. It had an Absurdly Spacious Sewer, not just one but two ruins of lost civilizations beneath Waterdeep, and an infamous ending, where the player was treated a window of text before dumping them back to DOS (the Amiga version, however, added a proper ending cutscene). The second, generally thought to be the best of the series, involves the party checking out an ancient temple for Khelben "Blackstaff" Arunsun. It had more roleplaying content and much better ending.The third game, assuming you're willing to acknowledge its existence, sends the player into the ruined city of Myth Drannor. It was not made by the original developers, and is generally considered a massive disappointment.A spiritual successor, Lands Of Lore, was created by Westwood in lieu of a third Eye of the Beholder after the split with SSI over creative differences.A remake of the first game was released for the Super Nintendo, and later for the Game Boy Advance. It was also ported to Mega CD, with music composed by Yuzo Koshiro. Note that this remake diverges quite a lot from the original game, both in game mechanics and in that it adds sub-boss enemies.
The Eye of the Beholder series provides examples of the following tropes:
Antidote Effect: In the first game, you can find potions of counterpoison in the spider level. Quite necessary, since at that time your cleric isn't high level enough to cast "Neutralize Poison", only the weaker "Delay Poison" spell, which just gains you some time.
Arbitrary Headcount Limit: You start the game with 4 characters, even when importing to the sequels. You may get upto 6. The second game also has an NPC that runs off, but he won't do it if you reduce your party size after recruiting him.
Disc One Nuke: The magic dagger Guinsoo, obtainable in the very first level of the original game. However, you may never figure out how to get it... Although it sounds impressive to have a +4 weapon at low-level, it really only deals 5 to 8 points of damage on a hit. Also, you don't know it is a +4 weapon, this might be more of a Guide Dang It territory, at least until you reach the Identify alcove, which you don't know is an Identify alcove.
The rust monsters in EotB1 will eat any metal item.
The gelatinous cubes in EotB2 can also destroy items on a hit.
The black puddings in EotB3 will eat your weapons if you attack them in melee.
Moon Logic Puzzle: Every dungeon level of the first game has a special secret that you can discover if you perform a specific sequence of actions on that level (the first level's is the aforementioned Disc One Nuke)... and the game only gives very obtuse hints about what those actions are. For example, put rations in the closet labeled "pantry", or eggs in the room labeled "nest".
The complete disappearance of the Stoneskin spell in EotB2, even with an imported party from EotB1, for whom it vanishes from spellbooks (and a Stoneskin scroll can't be saved either). See the Game Breaker entry for why.
The Turn Undead function also get modified between the two games, as mentioned below.
Old Save Bonus: The sequel can be started with the party from the first game — along with all their equipment, containing a significant amount of weapons and armor that outclass everything available in the second game. If you play it right, you end up with at least three +5 weapons and a dozen +5 darts, whereas the best weapon available late in the sequel is only +4.
Our Dwarves Are All the Same: Most of the NPCs that can join you in the first game are dwarves. All are fighters with An Axe to Grind and preferring heavy armor, practically identical except in stats. The dwarves that can be seen in large amounts in their camp are, other than a single exception, literally all the same: your basic bearded, heavily-armoured, axe-wielding type.
Most annoyingly the thri-kreen, which are so fast that almost without fail one of your front-row fighters will be paralysed before even having the time to strike on his own.
The mind flayers' psychic blast is a distance paralysing attack, and can affect several PCs at once. Your cleric better have several Remove Paralysis spells ready... and if the cleric himself is paralysed, you're out of luck.
On the other hand, if a beholder just paralyses some members of the party, you've gotten off lucky.
Schmuck Bait: If you're warned to not enter the room full of awesome magical items... you shouldn't.
So Long, and Thanks for All the Gear: Played completely straight with one character in EotB2 . A halfling you meet early in the game is locked up, and you have the option to free him. However, the first time you camp with him in the party, he runs off and takes, not the equipment he's carrying specifically, but some of the gear of the sleeping party members. Well, you should have expected it; he's a Thief (the Character Class). He even leaves a note basically invoking this trope by name.
Turn Undead: A power for the cleric or the paladin, along with the D&D rules. In EotB1 it is an automatic function, as long as the character is holding a holy symbol. Starting with EotB2, it becomes an action like any spell-casting, though not limited in use.
Undignified Death: Tod Uphill in the first game died by falling down into the sewer. He is not happy about this if the party resurrects him.
Ungrateful Bastard: At one point in EotB2, you have the option to help out a beholder stuck into a circular hole in the ceiling. If you choose so, it thanks you... and then immediately attacks the party because it's hungry.
Warp Zone: The magic portals, especially the room with five of them in EotB1.
A Winner Is You: The MS-DOS version of the first game is notorious for its anticlimactic ending. After defeating Xanathar, a simple message box appears, describing the party's rescue and the following celebrations - and then the game boots you back to the DOS prompt.
Wizard Needs Food Badly: Not so much of an issue though, as the game gives you more than enough rations to last until your cleric can learn a very useful "Create Food" spell, that instantly fills the entire party's hunger bars. The first game actually contains enough food to make it through without the Create Food spell — although adventuring without a cleric is a bad idea for other reasons.
You All Meet in an Inn: How the third game begins, complete with a dubious cloaked individual offering the party a job.
