Well I got started thanks to my wife. A room full later I'm sure she regrets it but I sure don't.

It happened back in 2005 while on vacation at Disney with my wife and son. We hit MGM a couple of times and my sons favorite ride was a Star Wars simulator. And if you've been to a Disney park you know that the rides typically empty out not into the walkway but into a store. In this case is was a "Tatooine Traders" loaded with Star wars stuff.
To put into perspective what Star wars means to me; I'm 36. The first movie I ever saw at the theater was Star Wars. I had the figures and play sets. The prize of my collection was the Millennium Falcon. One thing I regretted was selling it off as later on in life I thought it would have made a nice decoration in my home office. As a kid Lego was probably my favorite all time toy. In fact my son inherited my old stuff (Mostly Space sets) as my mom kept them when I outgrew them. (Yes I know, hard to believe but I outgrew Lego at one point. Social conformity I guess.)
So... back to the Tatooine Traders. Lo and behold there is a Falcon made of Lego!

I felt my childhood returning and just stared at the box for about ten minutes

before my wife finally (and painfully) pointed out. "Check out the price!" Dream dashed.

I put the box down and wandered through the store. Being my sons favorite ride we ended up going through the store about 8-10 times in a few days. After about the sixth or seventh time of me stopping and staring, my wife finally just told me to pick it up. She was buying it for me.

(Which considering we have a joint account really just means she approves of me spending "our" money)
So the Falcon (4504) was my first set. A few weeks later I spotted a Tie Fighter at some store. "That would look nice on the shelf next to the Falcon......" And since then I've bought everything that has hit the stores, only breaking down and ordering online once. (The UCS Falcon of course. Had that beauty preordered the first week it was online) and I'm about to start hunting down sets I missed out on cause I didn't start early enough. I'm a completist so I "need" them all, although I've convinced myself (partially) that I can live without the ones which I have newer versions of. (I could see myself getting some of those anyway

)
Some friends think I'm nuts most think the collection is cool.
