Part of it was having way more goods to buy, it was about double from 2014. It wasn't always as simple as just handing your tick sheet and paying.

In all fairness, 2014 had the VIP pass you could pay extra for. So you were able to get in earlier than the normal time on day 1, get in-line, and buy your goods before the keynote even started. I also think not having free t-shirt with the cost of the attendance or one being given away as part of the battle challenge also made up more buyers. Small things that add up, but the amount of items available this time around certainly is a contributing factor.
