I went to PAX South over the weekend with my wife, brother, and a friend.
I got the limited edition meowing box Exploding Kittens card game, Portal the board game (which comes with a steam key for Portal 2, so now I can finally play Mel Stories), the Dead Rising 2 Sledgehammer-Buzzsaw combo weapon pen, 2 Mega Man arm sleeves, tons of buttons and stickers, a shit ton of flyers and business cards, some portal knee high socks, 2 Protomen Vinyls, will update as I remember.
Towards the end of the expo, I went to go see a game I really liked one more time. I noticed a sign that said TVs for Sale, so my wife told me to ask about the big tv. Guy tells me one of the volunteers already called dibs on it, but the smaller 40" TVs were for sale, said he would sell me one for $100. They were also selling games and exclusive PAX pins. They had a deal with 4 games, but they were out of steam keys for one of the games. A little haggling later, I got the TV, the 3 steam keys for the remaining games of the deal, a 4th steam key for their new game that wasn't a part of the 4 game deal, a cowboy hat, an orange top hat, a steam punk hat, an inflatable cactus, and a PAX exclusive Ninja pin... for $115. Considering how much those 4 games and the PAX pin would've cost me, I got that TV dirrrrrrrrrrrrrrty cheap.
I also received my Wearable Mega Man Helmet over the weekend.
