No map, so expect to spend a lot time wandering around looking for stuff.
Poorly explained controls, I got frequent pop ups telling me to analyze something but no explanation how to do it. My scanner didn't do anything except send out a pulse, so who knows?
Confusing menus that rely on icons instead of words. I don't know what's what.
Meh, I can see how some people like this game, but it's not for me. I'd refund the game, but Sony won't allow it as I already downloaded it.
