I like threads like this, it reminds me of some good fun times over the years, and seeing all the items again. Some I missed out on, like the pants with the buckle and the chamber apartment, while others I was lucky to enjoy, like Xi.
For me, my favorite and most rare item to me is one of my newer ones, my Casino Roulette Winners jacket, which due to the writing on the back makes it the only one in Home, something i never though I would ever win.
Other favorites and rare items of mine are my Star Trek uniform (only available during a 2wk window at the end of 2009), my diamond EA poker bracelet and my RLS tracksuit (not so much the jacket, but I love the pants).
