What made you start modding?

I guess doom is where I started, I could loose hours designing maps. It wasn't in till morrowind that I started tinkering around with games that weren't first person shooters, I'm still working on my modded version of morrowind what once was a one gig game has swelled to about 8 gig worth of stuff. I've spent more time in the construction set than I have actually playing the game. LoL

Quite some interesting stories on how you people got hooked up!

I started on Rome TW.
I just found the textures lacking.
So I put my knowledge into making them better.
But then my HDD fried and I lost everything.

so then I left it for a while (Sulking really)
Then started playing Fallout 3...
WOW... Such a fun game!

Then I found the nexus...
Then I found the geck...

... Well... Then I made a bunch of mods!
