Oh I'm not either (Im on PS3), but it always fascinates me to see whats underneath the games skin. "What kind of effect causes this?" or maybe "What are all the little items names in the GECK?" I enjoy seeing the things ingame.
It's amazing how much stuff is in the GECK and game files that isn't anywhere in the final game.
Some of it seems to be only in there to confuse modders, lol. I made a http://www.newvegasnexus.com/downloads/file.php?id=37672 and my homemade frag grenade used legion money, like the coin shot shells. When I tried to make them in game it told me I didn't have any coins even though I had hundreds.
I loaded the geck back up and saw that the legion denarius had 2 entries in the geck, both were pretty much identical except one was used and the other wasn't. The first was called "LegionMoney1" and the other called "MoneyLegion1". I of course had used the wrong one.
