Summary: Fun game. Not too difficult, but not too easy. Did not come with glasses, but they are inexpensive and I'm not sure that I would want used glasses anyway. There is a 2D option, which is nice since the 3D play is kind of hard on the eyes for extended periods of time.
Summary: I grew up with arcade coin-operated shooting games like Operation Wolf, Lethal Enforcers, etc. Until the past decade or so, the quality of the console ports never measured up to their arcade counterparts.
