Man I should find out if it's cool / legal to show off the original design document for FEAR (the original name of Tribes, before it was switched to Tribes, and was solely single-player). Bioderms, all kinds of crazy stuff. That design doc was like 5 lbs and had 300+ pages of history. Truly crazy stuff. I have all the old design docs dating back to the mid 90s for that stuff courtesy of the old Dynamix guys (actually we have original TIM art, all kinds of stuff from the older games). None of this stuff is in digital form though. I saw a lot of this stuff fall out of the woodwork that had been lost to some old dark dusty storage room (everything from design docs to original willy beamish art, to a Red Baron jacket, and more). While some of this stuff was pointed back to Jeff T, who has a pretty impressive collection of stuff, anything odd, like the FEAR doc I tried to protect from disappearing and stowed in a safe place at GG. If anything it's just neat to know it existed.
Fact: The reason the name Tribes came about was because you can't trademark FEAR as a name (which is why the trademark on the recent game, F.E.A.R. is actually First encounter assault recon). Tribes was called Fear years before, and bioderms predate the name tribes in design.
