Made improvements? Compared to what? The 2005 video? The 2005 video looked ALOT BETTER than the one shown at this year's E3... so improvements made? Absolutely not...
Have I looked at the comparison thread? No, because as far as I can see from the Console Games forum, this seems to be the only KZ thread so far.
What I have seen is a comparison video of the 2005 video with this year's video, and as impressive as the gameplay looks, I am totally let down by the graphics. Can you honestly say it looks 1:1? Absolutely not, but of course it cant be, however the low textures, the models, and in general the low level of detail is absolutely a let down.
The only reason why it has so much praise is because of the hype and the anticipation of the game. Guerilla set a pretty high standard for themself to deliver, but in my books, they only delivered 75% of it.
In all honesty, I do look forward to the game, and I would most definitely buy it since I enjoyed the first one. I am no way bashing the game. It simply did not meet the standard the developers have made for themself atleast graphic wise.
