Demos for Sonic's Ultimate Genesis Collection and Up are now available on the marketplace. Coincidentally, the Sonic demo downloads ultra fast. However, the Up demo, which is over a gigglebyte, downloads about as slow as its protaganist can walk with that tennis ball cane. Actually, the Up demo is quite enjoyable -- in a Lego Star Wars kind of way.

The Sonic demo includes trials of Sonic the Hedgehog 3, Streets of Rage 3 and Space Harrier. Playing the demos reminds us that nostalgia isn't all it's cracked up to be.

Update: In case it was missed, Wolverine went live last night. Thanks for the backup, B1ggrandall.
