I will still take more than two hours to figure out if this game is playable or not, especially since everything is so random/buggy. And the framerate when loading scenery (looking in a new direction) currrently seems to depend on the the time of the day, because the geometry servers are overloaded or somthing.
After 6 hours of game play (sort of - half of that been spent looking at loading screens and trying out different settings) I'm still not sure. It's oh so promising but also so insanely buggy and random.
