I had a goal I wanted to collect one of every hat in the game. Didn't really care about the quality at the time. Just started buying uncraftable ones since they were cheaper. After I had gathered some I found collecting uncraftable hats more challenging then craftable hats. Since craftable hats are something everyone could get. I had fun collecting them with a friend of mine, especially when one of us bought a 'rare' one (they were already hard to get at that time too, nothing has really changed on that part).

I quitted +-8 months ago since they just kept adding new hats into the game, making it impossible to ever really finish. When I heared about the update that they removed the 'uncraftable' quality from the store I restarted trading again. Since I could now finish my collection. Making this collection one of the best finishable, challenging collections out there in my opinion!

After collecting every hat in the game I felt at peace and at first didn't knew what to do. So then I decided to start a new challenge for me. Trying to get every 'super rare' one (brain bucket, dead cone,..). I wasn't really planning on starting collecting a dirty weapons set, but it has the benefit you never craft a weapon you might need at some point. So everytime I craft now I don't have to think if I need that weapon or not, since I always have an uncraftable counter-part. Also started a group to meet fellow collectors at some point.

Now I just try to help the community a little by informing people regarding uncraftable items.

Edit: well, it got longer then expected (that's what she said)
