Billy Idol
Legend
I went on Thursday last year, and queued up fairly quickly immediately for the Vita corner. That ended up being a wait of 20-30 minutes or so, but it was cool to be able to try the Vita out and see various games being played on it. Amusingly, I played Smart-As (you get cards assigned at random for each of the games in there), which I didn't think was too great at the time, but now ends up the only game in that booth not being out yet.
Almost all of the big, hardcore stuff had these huge queues around closed booths that you couldn't look into while queuing, and that ended up being the bane of the show for me - I'd never go again unless I was certain they'd fixed that, there was something new I was sure to be interested in but which is not popular with the hardcore (like Move related stuff last year- I was very interested in various Move titles and it was pretty easy to see and play them), or if I'd get a press-pass like now.
Again, I hope they wise up eventually and just make a huge separate part of the show floor with all the 18+ stuff.
The reason those booth are closed is indeed the strict age restriction in Germany. They should really assign a 18+ area only...or better a 30+ area
