I'm not sure that I follow, crmurray.

Obsidian installs a folder with data files and an Obsidian app to an Obsidian folder that's fairly easy to find, like most Mac applications and games do. It even adds an alias called " Play Obsidian" to your Apple Menu, to make it clear that you need to launch the game with the Obsidian app. I'm not sure I'm a fan of the Apple Menu addition, but it's there.

Are you sure that you've run the installer? Or is the problem something else, like this game crashing on launch when you run it in SheepShaver on the latest macOS?

I'm wondering if someone on here can help me. I am trying to run this on my Mac OS 10.15 using SheepShaver. I am able to install but I'm not sure how to run the game. Any help would be great. Thank you!

Director Bill Davis was an interesting personality, he ran creative for Sierra during the early 90s. Often criticized by staff for running the company too much like a Hollywood studio, right down to storyboarding every game to minute detail.

That made for a number of games with puzzles that didn't go through much play testing and, while the presentation of 90s Sierra CD-ROM titles was certainly cinematic, it didn't leave much room for varied solutions, randomized events or even neat arcade distractions compared to earlier Sierra games like The Colonel's Bequest and Space Quest III. He also had a very unique visual style seen in EcoQuest and Pepper's Adventures in Time that's a bit like a rubbery CalTech look, which unfortunately isn't in Obsidian.

Not to downplay the other personalities behind Obsidian. It's a game that deserves more of a chance than it got... I do love this one in the same way that I love Phantasmagoria 2: A Puzzle of Flesh. Weird and wonderful, and dorky.

Hmm, this game had quite a marketing campaign (lots of ads in MacAddict and the like) but I never actually played it. All I remember is finding the ads to have pretty cool designs. hahaha Smile

yeah, and you've uploaded more than your fair share of stuff.

Check eBay every day, got about 7 saved searches that throw up everything we may be interested in, usually 70% of it is Championship Manager and The Incredibles here in the UK. Can't remember specifics, many months ago a great find came up at a great price on Buy It Now (notified by email), went straight to the link. Already sold. Less than 4 minutes and it was gone.
I'm sure these guys that sell the old games at silly prices ie. £40 / $60 are the same ones that outbid me when they come up for pennies - I've seen 2 copies of a game come up, both with bids at £0.99, I've bid £5 or so on the first and I may get a winning bid of £4 up until the last 20 seconds, then someone will outbid me while the second copy finishing 5 minutes later is still at £0.99. But I suppose that's the way it goes.

Sorry if I sounded terse but it always seems like there's just a few of us uploading stuff and everyone else begs.

At least in the States there's lots of deals to be had online, but you have to check every week, and you have to be careful not to assume that just because some jerk is charging a fortune for a game that he will actually get that price. Blink and you'll miss the real auctions where the game actually sells right away and for much less.

@ MCP:
Last time I was looking to buy it the price was at $50 and it was only available at =\ Apparently people decided to finally start letting go of their old games after Classic went away...

To get it to the UK, $44 cost + $15 shipping + $11 local tax + $15 local post charges (fee to collect the $11 tax).

Been there, done it before. A foolish waste of money in the quest to help preserve Mac software.
More so if another member of the site has the full set of discs.
Even more so when some of us here are willing to spend say $10 to buy a mult-disc title locally that has been requested, and make the further effort to upload all of it somewhere for all others on the site to download for free.

"I've been waiting twelve years to get to play this game"

One would think you could have saved up twenty bucks in twelve years.

I keep getting messages asking for other discs....

Is there any chance someone can upload all four discs? I've been waiting twelve years to get to play this game =(

This is game, quite frankly, is a work of art.
It's one of the few games I place among my favorites that I still haven't actually beaten.
Really tough puzzles.

Thank god the version released to mac had an updated soundtrack.

I say a page can have buy links or download links, but not both, for pure precaution.

Is this abandonware or not? If so, upload the full game.

Legally speaking, abandonware is still on a gray area, so adding buy links to something we're offering for free can be used as an argument against us. I say a page can have buy links or download links, but not both, for pure precaution.

Buy-links to Amazon are OK, I think.

Don't worry, MileStones. So it's a custom CD image. Okay. Next time, remember to point that out to avoid confusion.

There's nothing wrong with wanting to include information about your upload, but better include it here unless it's too long.

And why post something here if it's still being sold? Because the goal of this site is to preserve classical macintosh software whenever it is freeware, shareware, abandonware or mainstream. However, only free software can be uploaded. Commercial software must be linked to their respective owners, and resellers don't fall into that category. Hope that clears things out.

Sorry MacWise, that disk is actually a manually crafted one, it excludes all the big movies.
And I included the Amazon link only for other people as info and if can still be bought via the developers why should post a game which is not abandonware... I can remove it if you like...

Where are the links to the other four disc? You can't complete the game with just the first one. And why is there a link to buy it on Amazon? The purchase link is only to be used with the original developer or distributor, and both Rocket Science Games and SegaSoft are no longer operational.
