I took my cabinet to Quakecon back in 2005. The cabinet was located out in the open where people could just swing by and play a couple games. The cabinet was a huge hit in one of the toughest gaming arenas in the world. One morning about 4am,
Johnathan Wendel aka Fatal1ty, come out to the Bring Your Own Computer gaming area. He was checking out the cabinet and playing a couple games here and there. He fired up Mortal Kombat 2 and we started playing. Eventually we had about 100 people all standing around watching and people taking turns fighting against him. He ended up choosing a random character for every match, finished every round with a fatalities and whatever other finishing moves there are in the game. When all was said and done he had gone through 50 people, non stop, and he lost only 1 round which was to myself. It was actually quite impressive to witness.
Since Quakecon is hosted by id Software, several game developers are always around, including the legendary John Carmack. Yes, Carmack himself stopped by and checked out my cabinet.

Also, during one of the overnight periods someone walked up and asked if I had NBA Jam on the cabinet. Of course we fired it up, played around and he began doing several different things to the game that I've never seen done before. He eventually explained that he was one of the developers that worked on NBA Jam. When I asked if he was upset that I was emulating his game on my cabinet, he said that he was just happy to see his creation being played how it was supposed to be played. I also shared a bunch of my files with the guys at Infinity Ward, the creators of Call of Duty.
I've got to say that that Quakecon 2005 was probably the most fun that I've had with my cabinet. Even though I didn't play my cabinet much during the event I got to see my cabinet being enjoyed by many and bring back memories for lots of people.
I should have pics of some of the devs that stopped by to play as well as the big group playing MK2. I'll try to update this post later with the pics.
I do have to add, that being able to watch my kids be able to play these arcade games is one of the best things ever. When I built my cabinet the kids were 3 & 7, they are now 9 and 13. They have been able to grow up and having the cabinet has made them appreciate the older classic games. It's really nice to see 4 year old playing Frogger and remembering back when I was 4 years old... playing Frogger.
