1) MagiQuest Online's Older Brother: Myst Online: Uru
You may or may not have caught this, but MagiQuest Online, while produced by Creative Kingdoms, the makers of MagiQuest, was developed by Cyan Worlds, the makers of Myst. The most recent Myst game, Myst Online: Uru was not originally created by Cyan Worlds, but, after a few counts of being shuffled around, ended up in the hands of Cyan Worlds, after all.A little poking and prodding (actually, while trying to determine MagiQuest Online's Minimum System Requirements) led me to the discovery that MagiQuest Online is, in fact, built on the Myst Online: Uru engine.
What does this have to do with anything? Well, the following bet-you-didn't-know items are all based on this shared lineage... things that were "already in there" when they started building MagiQuest Online on top of what had been Myst Online: Uru...
