Is it purely a 'gotta-have-them-all' mindset, or do they actually serve some purpose?
I notice that you are able to sell them on a community market. For a test I listed one, and someone bought it for 50p. Not exactly a huge amount, but I don't understand why someone would spend real money on them.
Am I missing something?
Are they redeemable for games or money off vouchers or something 'tangible' that I'm missing?
