[Edit] Prince of Persia Classic Comparison
I wrote earlier about Ubisoft's remake of the classic Prince of Persia by Jordan Mechner. Downloaded it last night, and it's fantastic, especially if you remember playing the original for many misspent hours of your youth. I just came across a great video on Gametrailers.com which shows off differences between the PC, Genesis, and Xbox Live Arcade versions - good for a trip down memory lane.
Also of interest is the rumor (which I can't find right now) that Jordan is working on another side-scroller for next year. Karateka, anyone?
[Edit: Just read through the whole Wikipedia article on Karateka and came across this gem:
The Apple II version came on one apparently single-sided disk. As an easter egg, a second version of the game was placed on the flip side of the disk. If one put the disk into the drive upside-down, the game played identically to the first side, except that the game was displayed vertically flipped. According to Mechner, this was done as a joke, causing naive users to call tech support and ask why the game was upside-down. Invariably, they would receive the reply, "take the disk out, insert it right-side up, and reboot".
Mr. Mechner has just leapt to the top of my personal game god pantheon.]
