First encountered Marathon in 1996 w/ M2. I've owned the Mac Action Sack (loaned to a "friend" and haven't seen it in five years), and d/l some of the bigger scenarios that have been made by dedicated Marathoners.
My hat is WAY off to the makers of the Tempus Irae and Rubicon scenarios. Nardo, Chris L and Co. --some incredible work!!
I dabble with map making but there's sooooo much involved I tend to produce sketches that I think have potential but never really go anywhere. Yep. I'm a noob.
