I remember the way U.S. game companies took these games and bastardized them to make them look more american.
The thing was: U.S. game companies didn't believe at the time that "japanimation" would be a major seller to gamers so they had to rework them to make them look more American. That would also explain why many games for the NES, SNES, T16, TCD, SMS and GENESIS had their cover boxes reworked from their original anime designs to make them look more American.
Had anime been as huge then as it is now, that would never had occurred. Shame really, because the original anime coverarts looked far better than the american fantasy art crap that they replaced them with.
