I was introduced to Super Meat Boy and Borderlands 2. Also some cool games like Transistor (2014), and Contrast (Really cool game, twenties looking, just innovative, coming out in 6 months.) There were other indie games that didn't survive my interest after playing them for 5 minutes: Journal, Tengami, and others I don't remember.
I met the Spaceteam developer! So exciting. I had him take a picture with me and he seemed surprised that I wanted a photo with him. SPACETEAM!
I met a 21 year old boy/man who quit college and built his game The Swappers, and it was well done. And it made me jealous of him! I want a game.
So being surrounded by so many people pursuing their dream of videogame development definitely made me want to build a game. I technically have done game development (Ancient Anguish WOO!) and I just want to make one game. At least get one crappy game developed and out of the way. Even if it's a pixel flying back and forth.
PAX was inspiring and tiring and invigorating.
