I thought the same thing, until I read the interview and found out sealed collectors buy multiple copies, sealed, and unsealed to which to play the game. So the only logical reason they are collecting, besides bragging, is for the resell value when they eventually cash out of the hobby.
What a waste. The main reason for games as investments is because you can play them in the meantime. Rather than collecting sealed unplayable games, these guys could be researching, purchasing options, and making more money in a month than they could over the lifetime of the collection. Plus, if not for the newness of those games, that's a pretty mediocre top 10.
Den, we've been patient (perhaps a little too patient) when it comes to all the self-promotion, but the staff has had enough - you are officially on notice. So much as crane your neck towards that sealed games site again and I will personally recommend you for immediate banning.
