As a commercial game download service, Good Old Games (GOG) has been bringing classic PC titles back to life for a few years now. Just today, GOG announced that the IBM PC version of Ultima IV: Quest of the Avatar is now available as a free download over at their site.

Ultima IV has been available on the 'Net as an authorized free download off and on over the years, but it's always nice to have a trustworthy place to get it.

While you're over at GOG, check out the site's other offerings. I personally love GOG because they distribute original, full games without DRM. That is very important.

Up now on Technologizer.com is my recent interview with John Linnell of the tech-savvy rock band They Might Be Giants. Linnell and I discussed his personal computer and video game history, how he's integrated computers into his music career, a fierce Tetris addiction, and gruesome encounters with X-Acto knives. I hope you enjoy it.

By they way — Happy Birthday to Mr. Linnell, who turned 52 yesterday.

CYBERSPACE (echo, echo, echo…):

The future of mankind or an ingenious scheme to sell virtual furniture for real money?

It's been a while since I've done a slideshow where I attempted to quantify the unquantifiable and rank a series of things in order from least to greatest. I'm typically not a fan of the format because the results are always subjective, but I still think it works because it stimulates public thought and gives me a good excuse to both entertain and educate on a subject I love.

The subject, in this case, is online worlds, where people gather together in virtual space to buy/sell mouse-crafted Furry outfits, chat about LARPing, and construct entire worlds filled with simulated genitalia.

So without further ado, I present to you "The 11 Most Influential Virtual Worlds of All Time" over at PC World. I hope you enjoy it.

When you're done reading/pounding your fists, feel free to tell us about your favorite online worlds in the comments below.

"Now you too can play Pool 1.5″

I have fond memories of Pool 1.5 for the Atari 8-bit computer line. I remember finding a neglected copy of it in the back of our Atari disk box as a kid and playing it for hours. Despite it's age, I still enjoy playing Pool 1.5 more than any other billiards simulation.

The "1.5″ designation in the name is interesting and somewhat unusual for a game. I assume it's a version number, but I've never heard of, say, "Pool 1.0." Maybe it's a title that metaphorically suggests improvement on the real game of Pool, similar to how we say "Revolution 2.0″ today. Or maybe not.

If you get a chance, you should try it out. The game holds up surprisingly well.

Have you played all 45 games seen here?

Scott Adams adventure games are nigh-but-legendary in the history of computer gaming. Mr. Adams' company, Adventure International, published dozens of interactive fiction titles (some with graphics) between 1978 and 1985. They were available on just about every computer platform of the 1980s, so it's likely you've encountered at least one of them if you owned a computer at that time.

Early Adventure International games sported a relatively simple input parser (usually two words, a verb and a keyword) compared to Infocom fare, but that didn't stop Adams' captivating games from spreading far and wide — both legally and via piracy — across the personal computing universe.

Regarding the two men pictured in the ad above: I'm guessing they're Scott and Alexis Adams, the two men behind Adventure International. Turns out Alexis is a woman (see comments), so it's unlikely one of them is her unless she was fond of wearing drag.

…Oh, and I know Jason Scott will say something if I don't mention Get Lamp, his new documentary on text adventure games. I haven't seen it yet, but I hear it's great.

If you've ever had half a heap'a wunderin' about the history of stereoscopic displays in the computer and console gaming realm, mosey on over to PC World to check out my latest slideshow. There you will find 21 lovingly-crafted slides that tell the long and varied story of 3D stereoscopy in video and computer games.

Writing about video game history for a computer-centric publication has its ups and downs. While the publication is top-notch, sometimes I think video game fans miss out on the best of my work. So if you think you know someone who might like this piece, please spread the word.

After this yet-another lengthy visual article, I'm thinking about wrapping it up in regards to epic slideshows. Sure, I'll still do slideshows, just not ones so very, very long and involved.

After you're done checking it out, I'd love to hear about your personal history with stereoscopy in video and computer games.

And don't forget: the Nintendo 3DS comes out in the US on March 27th.
