Saw the post about the BF4 dog tags and had to dig these up! They actually stamped both your full name and a handle of your choice into the tag.

These were given out at the GeForce LAN 6 by Nvidia in 2011, which took place aboard the USS Hornet aircraft carrier in Alameda, CA. EA/DICE partnered with Nvidia to showcase Battlefield 3 ahead of its launch and they had a bunch of PCs set up onboard to demo some maps and to host a tournament over the weekend.

Bonus pictures from the event itself that I took. A friend and I had BYOC ('bring your own computer') tickets that let us lug our setup from home to the event and the aircraft carrier lifts were used to transport people up with their gear. They also had bunks available to sleep in overnight for those that didn't want to be at their assigned seat for 48 hours straight lol (they did let you leave your PC to go home to sleep and come back anytime which is what we did since we lived close).

Probably my fondest memory of any gaming 'event' ever as it's hard to top a LAN party in an environment like this with the hype for a game like BF3 had at the time. Looking back on this it was truly impressive how they pulled off this event given all the logistics involved.
