5. Gun Griffon
A sub-genre that hasn't had much love in recent years, that of the giant robot mech, Gun Griffon was a great example from back in the day. Your mech had the ability to unleash all kinds of attacks, mostly utilizing missiles and machine guns but perhaps the most fun came from the ability to leap high into the sky and rain down death from above. The graphics have actually held up surprisingly well, considering it's age and the limitations of the console at the time. The missions all followed a fairly similar patter of go to location A blow up thing B, but blowing things up is cool. A sequel came out on PS2 but didn't quite live up to the original. https://www.youtube.com/watch?v=pZdYDe47nyU
