Gameboy game. Starring Firebrand, the notoriously obnoxious boss from Ghosts and Goblins, this is basically a platforming type of game, although for some reason the platforming areas are separated from one another by an RPG-style overworld with random combat. It was fun enough, but super short. Like, beat it in a single leisurely evening, short. Its main claim to fame, from my point of view, is that it would give rise to two sequels, the second of which, Demon's Quest, is an excellent SNES game.
Eye of the Behollder
I finally beat this game into submission, but I didn't enjoy doing it. I know to some people this game is a great classic, and hey, different strokes, but I found it dreary and unpleasant. Carefully and tediously mapping a twelve-floor dungeon while occasionally stopping to engage in irritating and poorly-conceived combat. The combat is usually pathetically easy, thanks to game mechanics that allow you to literally move in circles around your enemies, constantly hitting them as they turn around to try to face you, but occasionally takes a break from that to be grossly unfair--turn around a corner and oh shit, mind flayer paralyzes your entire party; might as well reload. On an individual level (ho ho), the dungeon levels could be interesting, but there were so many of them, and you always knew that the "reward" for clearing a level would be to do it again with the next one, and uggghhhhh. Might and Magic was a larger game, but understood the value of breaking the game world up into various types (overland, castles, caves, etc) so that you never spent so much time in any given place that it became tedious.
The last boss of Eye of the Beholder, by the way, is a beholder. Sorry, was that a spoiler? Anyway, I want to share the last-boss experience, as being pretty typical with my experience with this game. A beholder, for non-D&D types, is a kind of super-monster; it's immune to all magic, and can use death magic and disintegration magic at will, as well as other various powerful attack abilities. The beholder always gets to go first in this game, so the first step of beating the beholder is to reload until he doesn't start out by massacring your party. What you're supposed to do is use a certain magic wand (the one magic item in the game that effects it), which knocks it back a space, to try to push it into a trap. After that failed spectacularly and repeatedly. I tried Plan B; luring it into a room, and dancing around it as I described above. That worked better, but eventually I'd make a mistake, and then half my party would be dead. So I finally devised Plan C. The door leading up to the room with the beholder in it can be opened on either side, but if you leave the room--while desperately running away from a beholder, for example--it closes behind you. When that happens, you're safe, because the beholder might be a death-magic wielding superboss, but it still can't open the doors of its home. So.
1. Run away.
2. Open the now-closed door. The beholder is randomly wandering around the room, and doesn't react to you.
3. When it appears two spaces in front of you, run into the room, whack it once, and then run backwards out of the room. The automatic door will safely close to protect you before the beholder can turn around.
4. Repeat Steps 2 & 3, and destroy the beholder without it ever managing to attack you.
You can import your party into Eye of the Beholder 2, which I also own (I picked up a collection of a bunch of Gold Box games at some point, which includes the EotB trilogy among others), but ... maybe later. Much later.
