You also seem to have ignored the "still in the prototype stage" thing, which means they're still testing what does and doesn't work, graphics come later.
Don't bother, you're just wasting your time. I read the comments, here, and on YT, saying the graphics are crap, and what have you. But after watching the video myself, I thought they was fine. I had expected to see something that had truly bad graphics. But seeing it first hand just gives me a stronger opinion that the people QQing about the graphics are nothing more than graphic whores.
The video did give me the 'Dead Island' feel, so I won't argue with that.
As for the other comments from people saying it looked boring. It's as you say Prototype Stage, people hold onto your judgement for the BETA build. It's during beta when things seldom change. --- Some idiots on GFaqs need to learn the difference between trolling, and a different opinion. If you're offended by this sig, you're one of those idiots.
