Mystery Mansion: Finished!   2 comments

As predicted I was quite near the end, but I had to do the extreme measure of opening the data file with a text editor to get there. It was worth it for the ending (which, I’ll be honest, is not something I’d ever expect to say for a Greg Hassett game, but here we are).

Mostly here for spoiler space: this is the image leading Greg Hassett’s article “How to Write an Adventure Game” from the book Big Computer Games published in 1984.

After the shenanigans in my last post, which included bringing down a force field with a phaser and chiseling a dime out of rock, I made it to a graveyard where I found out the objective of the game:

Nearby was a phone booth with a phone book. (Conveniently, the faux-dime made out of rock worked on it.) I suspected that the goal above would be reached via dialing the right number, but no permutation of >READ BOOK yielded a number; it wasn’t possible to look up the name HOGGS or the like.

Fairly soon I was out of obstacles, except for a large rock which didn’t have any writing and didn’t yield to any of the adventurer commands of TWIST / TURN / PULL / etc. After fruitless wandering back and forth I decided to open the file in a text editor and hope for the best.

I had overlooked my Star Trek references: if a phaser is in a game, *always* check it for multiple settings. Specifically, >LOOK PHASER revealed it had settings for REVERSE (the default) and DESTROY. I changed the setting to DESTROY and went back to the large rock:

This opened up a new passage into some secret archives.

Fortunately, letters on keypads haven’t gone out of date yet, so I was able to convert the clue into a number, and the glorious ending.

Just for reference, a quarter is about 5.67 grams, so 12 million of them would weight 68 metric tons or just a bit lighter than a large dinosaur. It’s going to be fun toting away the haul! (This is assuming the main character even survived the deluge.)

Most games from this era had perfunctory endings. I suppose this one did as well — just three sentences! — but the Monkey’s Paw style twist was enough for me to be happy. (I liked Zork’s ending as well as Local Call for Death’s, but I can’t think of any others from 1980 or before that were memorable.)

Mystery Mansion (1980)   7 comments

In our first namespace clash, Greg Hassett released Mystery Mansion in 1980, not to be confused with Bill Wolpert’s Mystery Mansion from 1978. (Not to mention Robert Arnstein’s Haunted House or Roberta Williams’s Mystery House. I haven’t got to it yet, but there is another 1980 game by John O’Hare called Haunted Mansion.)

Here’s a handy guide for keeping track of spooky domicile text adventures.

(Before I get started with the game itself, I’d like to thank Brian Decker for letting me know he found Greg Hassett had released his games into the public domain, leading Ira Goldklang to upload the entire set to the internet. Mystery Mansion wasn’t available anywhere until last year when this happened.)

This was Mr. Hassett’s first game done originally in machine language. He ported his prior game Enchanted Island to machine code and called it Enchanted Island Plus, but it was still essentially the same game; Mystery Mansion was designed from scratch in machine language.

Ad from Micro 80 magazine.

The premise is simply that “you have been called by a strange dream to a huge mansion. What you are doing here is part of the mystery.” There’s no treasures to collect, but not a lot of direction, either. I didn’t feel like the game was as aimless as Battlestar, because there’s enough tightness to the geography that it was always clear where the next obstacle was.

It does come across as a better game than his previous ones, by a multiplier. It’s nice in a “scientific” sense because he doesn’t change that much of his style; since Mr. Hassett essentially changed only one variable it’s more obvious what led to the improvement. The puzzles are still quite simple (you have poison, cheese, and an evil rat: what do you do?) His main innovation was to be more careful with the structure.

The game starts in a linear way: passing through a door or secret passage causes it to close, so you’re moving from small area to small area. There’s one point where you can leave something behind. It was genuinely interesting (and not, as I would expect, irritating) to solve this puzzle, in that I had to think of not just the tools I had, but a tool I could have had access to in the past had I approached a certain situation differently. This violates the essential rule in adventure game design that you can’t block progress by a prior action, but this is a special scenario in that a.) it happens near the start and b.) it takes about 60 seconds to get back to the puzzle in question. (This kind of design can still be very, very painful.)

After the linear section, the map opens up to a slightly larger but still blocked section. The left section opens up via a lever, and solving a puzzle there allows passing a zombie, opening up the third and largest section.

The overall effect is a sort of overlapping going on where solving puzzles leads to doubling back over the game’s geography in new ways. Even with very basic room descriptions …

… the structure gave enough of an “adventurer feel” that playing the game felt like exploring an environment, rather than filling in a bunch of map boxes.

I did finally discover why my character was summoned to the Mansion, but I’m stuck on what might be the last puzzle, so I’ll save talking about that for my next (hopefully last) post.
