Had to slap my head over this. Yuu Yuu Hakusho was a popular anime over here when I was a kid but since the game was SD and Japanese, I didn't realize I was playing a game about the anime until I squinted at the image.
Still holds a special place in my heart for being the:
1st rpg I've played before I knew what that word was about
1st action rpg I've played where it didn't revolve on puzzles but on kicking ass (something I only rekindled when I played Shenmue)
1st full modeled rpg characters with SD counterparts (again, something I didn't encounter again until I've played FF7)
1st game where special powers change in appearance as they grow stronger instead of having to buy and equip them
Only game I played where there's a brief sequence where a guy on foot was chasing a car
1st game I played where you can switch characters and they weren't a pallette color design of their counterparts and all had different moves but wasn't a fighting game
1st game I played where you beat up characters to recruit them and the characters were bosses (which made them extra special for the time)
1st game I played where the bosses had more than 1 form
