Game Innovators Pick Their Favorite Titles
Thanks to Ludology.org for pointing to the Georgia Tech game morphology project, which, although still in development, has asked famous creators and academics for their favorite games of all time. Interesting picks include Warren Spector's kudos for Ultima IV ("Wait, you mean games can be about more than just killing
things? Whoa! This game, with its ethical underpinnings, changed my life"), Henry Jenkins' choice of Myst ("not a great game from the perspective of game play... [but influential because] it brought some degree of middle class respectability to games"), and Will Wright's picking of Pinball Construction Set ("[a] heavy influence for me - construction is fun.")
If you've never played Ultima IV, you should, even if you don't like RPGs. It's worth your time. Luckily, Richard Garriott (aka Lord British) has made this easy to do by releasing Ultima IV as freeware. You can download the game here and the documentation here. Also, an upgrade patch has been created that improves the graphics and sounds without mucking with the game mechanics. You learn more about Ultima IV as well as download the upgrade here.
One other thing, it's a long game and even if you don't have the time to play it, download it and play through the introduction (10-15 minutes tops). There are a series of ethical/moral questions that determine your character type and they're really interesting. So interesting in fact that fans have reproduced the 'quiz' on the web so if you're really not into downloading the game, you can still take the Ultima Personality Test.
