Let's compare Spy Hunter
I love this guy's vids, but MAN! He sucks at games!
Yeah, he blames the mouse (emulation on computer), but it really limits how great a comparison like this could be. For example, with more effort, the comparison could be AMAZING:
(1) Show me how (if) each version has special weapons (I want to see a missile take out a helicopter).
(2) I want snowfields and ice!
(3) Examine the enemy AI behavior (for example, the ZX Spectrum was hilarious because 99% of the cars destroyed were crashing themselves!
(4) I don't remember being able to blow up the special-weapon truck in the arcade version, was it possible? Regardless, I was never this stupid and loved using the special weapons.
I played Spy Hunter a lot at the arcade back in the day, but the NES version was pretty darn good (IMHO) for the time.
