Don't listen to the hater? You haven't even played it. The game, while it does have potential, is just garbage, mainly because of performance issues. I have a HIGH end machine, and I had all kinds of lag, when I can run Oblivion maxed out. I really liked the ideas, but the targeting was crap as well. And the environment IS endless, that is one of the problems with it. There is not enough direction to the game, so it is incredibly confusing.
Of course, I only played a pirated copy for about 20 minutes before I got too frustrated, so I will likely give it a try when a legal demo is available.
