Thought I would share my thoughts on the London 3DS event too.
I went the the 1pm time slot, I had my girlfriend and a friend with me and was planning to abandon them outside while I went in but was told that it should be ok if they could come in too. So surprisingly I had two guests with me in the event.
As with everyone else the event started off with the weird floor thing that lit up to explain spot pass, the cheesy speech, live street fighter fight and the resident evil dark room walk through. Then Jonathan Ross was on a tv introducing the event. After that the doors opened and it felt like being at Wonkas chocolate factory, there were more than enough 3DS's for everyone to play, around 20 people were at the event.
The first game I played was Resident Evil Mercs and when I got on the DS I went to press the start button but soon realised it was the power button and forgot that the start button had been moved, I then had to find my way back to the in game screen.
After all that I finally got to play the game and was bored pretty fast with it, the 3D was pretty good but not as good as I was expecting.
I then moved on and saw that my girlfriend was playing Lego Starwars which didn't look too bad. After watching the lego game for a min or so I had a walk around and saw Ridge Racer and Steel Diver but walked straight past to Dead or alive.
Dead or alive was good fun, at the start menu it have a level that could be looked around with the gyroscope and the graphics were on par with a gamecube game.
I then moved onto Kid Icarus which blew me away, I even had a stylus in a holder in front of me which made the controls feel really good. The 3D in this game were deficiently the best I saw all show. The on ground parts were a little odd requiring you to swipe the screen to look around but I soon got used to it.
I then played Pilot wings and had double vision when playing it and had to adjust the slider to remove it. I had to use the 3d slider quite often but the game was fun enough to ignore the annoyance.
I then got to play Zelda but not for long as we were soon shifted onto the next room. Zelda wasn't the prettiest of games at the event but the character models looked great.
In the next room I had a go on the camera which didn't work to well in the not very well lit room, The mii creator was funny but probably not the most accurate thing in the world.
Face raiders was fun and used the gyroscope well.
The next game I played was the augmented reality game which was very impressive and graphically looked much better than the videos I had seen online. This was one of the highlights of the event.
Other games I played were Monkey Ball, Raving Rabbids and Nintendogs. Surprisingly Raving Rabbids was quite fun and much better than what I was expecting, 3d looked good too!
They had some 3DS's with 3d trailers on which included: Sky tv, animal crossing, Mario kart and Paper Mario. Paper Mario looked great in 3d and was one of the best games along with kid Icarus to use the 3d.
I looked at the time and realised that I had been at the event for 55mins and decided to leave as I had tried everything in the second room. I was really surprised that we weren't shooed off but allowed to stay much longer than I thought.
Oh yeah, the colour blue 3ds isn't as bad in person compared to the pics online.
Over all I thought Nintendo put a lot of effort into the even and was one of the best events I had been to, mainly due to no queuing.
I am now even more excited to get my 3ds next month.
