I'll name some I have discovered recently.
Mysteries:
Final Fantasy VII
You know in Corel Desert Prison, right? That there is a manhole you can go into that has an empty treasure chest? That mystery has been solved (a "Red Man" was inserted there ages ago to test the graphics, and there was supposed to a ticket for the LOVELESS play in the box) but did you know there is ANOTHER treasure chest in the Desert Prison that will always be empty? It's located in the area with the save point. Save there and load, and see for yourself. Upon loading, the treasure chest automatically opens and there is NOTHING inside!
Easter Eggs:
Final Fantasy VIII
When you're at that missile silo or w/e. When you are setting the Error Ratio for the missiles aimed at Balamb Garden, go to Equipment panel, and hold the Up or Down on the D-Pad as well as Triangle and O AT THE SAME TIME, and you'll see an animation of a Galbaldian soldier dancing or something. The Strategy Guide pointed this Easter Egg out
