I attended Day 1 of the first annual Got Game Conference in Amsterdam. Dedicated to "perpetuating and growing the video game industry through the exchange of knowledge and ideas," the event provided an excellent opportunity to meet the local gaming community as well as some big-brained industry visitors.
The best part, however, was the branded energy drinks that were given to attendees.
I haven't seen this before, but it's a fantastic marketing idea, given the audience of app developers and gamers.
I don't know how much they cost to produce (I have an email out to the event director to find out), but it's something I wish I would have done for the last Boulder Startup Week -- though there's a good chance that Boulder's health-conscious nerds would have run me out of town for trying to pump poison into their veins.
