Legendary Axe 2's art is indeed misleading. It uses the character from the first game that doesn't even appear in 2. I have Legendary Axe 2 but mine is card only. I didn't even notice this till the full size art was posted.
What's up with islands? Get more land.
What's up with deserts? Get less sand.
LA1 was called Makyou Densetsu (Legend of the Bounds of Evil) in Japan, programmed by Aicom.
LA2 was called Ankoku Densetsu (Legend of Darkness) in Japan, programmed by Atlus.
The Japanese publisher for both was Victor, so they probably called the naming shots.
I like the Mega Man boxart..
