Really not too dissimilar in composition to the actual Monster Hunter Tri box art. It's an armour-clad warrior, sword in hand, about to go toe-to-toe with a belligerent lizard. The real difference is the art from 24 years ago is much more... restrained. For starters, we just don't get sensible-sized swords like that any more. Swords today have to be physically impossible to hold - humongously proportioned pizza slices of death capable of eviscerating entire skyscrapers in a single blow.
And the dragon looks wimpy. Enough to impress the easily impressed 8-bit kids at the time, but those kids were full of unregulated food additives and MTV so they were in no fit state to know any better. Put anything less than a 20 storeys high mega-beast on the cover of a game today and the kids would literally point and laugh and then go buy Call of Duty instead.
