Fun & Games
Ok, here's the deal so far...
For this page, the absolute simplest thing I could think of was to have the games open in popup windows that call nothing but the swf file itself. The window opens at 800 x 600, but it can be resized and the swf will stretch with it.
Of course, Gem Mine has an odd glitch. If it wont start, try hiding the popup window (minimize it or put another window in front of it - just hide the display area) and then click the link again. Very strange bug, but I like that game...
