Q: Hey, I thought Marathon needed serial numbers!
A: The versions released with the Trilogy Box Set were stripped of the serial number code. These 
will work fine - as long as you're not trying to play with folks who are using older versions.

Q: Wow... can I do whatever I want with this stuff?
A: NO. Bungie still holds the copyrights to these files. They're allowing them to be distributed 
for free (mostly because you can't buy them any more) - but they're still Bungie's intellectual 
property. You can't, for example, sell them.

Thank you!
