I was there on Thursday and Friday with three friends. Two of us had never been to an exhibition as big as this and we were both blown away by it. I was already prepared for the queues so it didn't really impact on the experience, apart from the Dragon Age queue at 2-3 hours meaning it was a no go for us.
The best experience: Playing Alien Isolation with Oculus Rift! I was a nervous wreck when I came off it but it was worth it.
It was pot luck that I got this game after an hour of queuing too. I'd already played the demo the previous day putting it at the top of my wanted list and playing it with the VR headset really showed off the kit and the game, although I think this combination would be a bit too scary for me! Every time the Alien was about to get me gave me a heart attack, particularly when it got me from above and when it spotted me in the air shaft and running after me pierced me from behind. On one occasion its claw appeared over the headset! I probably jumped and swore to the amusement of those in the queue.
Other highlights:
Bloodborne (and the charismatic Sony guy sorting people in the queue - he was brilliant). I only played it as I accompanied my friend in the queue but I was very impressed. I didn't have the patience for Dark Souls but I really feel I want to give this game a fair shot. It was visually beautiful and my crow cloaked agile character was striking too.
The Evil Within. In the Sony booth we tried out Alien a few times between us and then we all watched as one of us made their way through a level of Evil Within. I hadn't even followed this but it's now getting bought.
Fable Legends. Mainly because the 4 of us could all team up. It was so much fun we queued again the second day in a longer queue while listening to the xbox stage talk about the game and hand out cloaks. I wanted one but even when we won against the villain in the game only two of us got cloaks.
Sunset Overdrive: I wasn't as impressed as I thought I'd be as what was on show just felt like another multiplayer game with a bit of tango thrown in. I would have preferred to just mess about in the open world main game, grinding and doing what the hell I liked, instead of thinking of competing for a score on my first ever go - I came last, this annoyed me. That aside I did enjoy using the various, and rather unique, weaponry on offer and taking down the huge mutants while grinding. Still hyped for the actual game.
The Order. I was shocked when the opening had infact stopped and it was actually gameplay! Steampunk heaven basically with weapons to die for. Only criticism we found was if it didn't add more variety to the gameplay it would get boring quickly. But in the short level I played I liked it very much.
Alien developer session. I think I was just a bit excited by the whole of egx so going to a developer session was pretty cool, especially being on the game of the exhibition in my eyes.
Splatoon: We sneaked into a closed queue at the end of Thursday to play this. It's a pity I wasted time shooting the walls but nevermind. I had fun playing it but needed more practise with the controls as I'm not used to the wii U controller. It was satisfying sneaking around in the paint though and splashing it everywhere.
Destiny: Would have liked to have tried the SP but it has to be said having two full teams go head to head right there was pretty cool. The hover jump function was satisfying!
Drive Club. A smooth racer that felt good to play; something I could do with on the PS4.
Other stuff:
Assassins Creed Unity presentation - I'm excited to scale Notre Dame. Got a rather nice free map too.
Lego batman 3 - the usual lego treat.
Trials DLC - only a very quick go, if you like Trials you'll want this.
Infamous First Light - more pretty super powers.
Sherlock - it seemed interesting but we didn't have time for its slow pacing. I did like it's implementation of the TV series' display of Sherlock's thinking.
Far cry 4 - I went up in an aircraft to shoot from above but got shot down flying around not knowing what I was doing...
New and Tasty - couldn't get my friend off it.
Didn't get chance to try:
Hyrule Warriors
COD
Batman Arkham Knight presentation
Yoshis Woolly World
Battlefield - although I watched people playing it
and various indie titles.
Shadow of Mordor
