My personal Gamescom highlight was clearly Enslaved by Ninja Theory. I just love the scenario, atmosphere and graphics! I hope the final gameplay will also be improved over Heavenly Sword, but let's see..
Here are some links and pictures:
Second highlight for sure were the FMVs of Star Wars The Old Republic - wow, they seemed actually higher quality than the films' CGs (except for the super-obvious matte paintings in the background during the first minutes)..
But the game itself is not my cup of tea, though, I fear...
The rest of the show? Lost in the blurrines of decibels, Kinect hype, 2h waiting queues and hordes of people..
