Heh…I just got it of the Virtual Console a couple months ago…
As far as I know, the reserve tanks are there for either when you want to manually restore energy, as well as if you run out of energy. When you feel that you are low on energy, and you need it now, you can manually activate a reserve tank to heal you by 100 energy. Or you can put the tanks on auto, at which point they will activate upon you reaching zero energy. The manual is nice, but I leave it on auto all the time because that way you have a backup if you die.
Yeah, I hate Maridia. Not the actual atmosphere, I love that, but all the dead ends and one way passages really get on my nerves. Draygon was awesome, though.
I loved killing Draygoon, I would always grapple onto a broken turret, it was just too much fun killing him like that, than any other way.
It was Phantoon I had a hard time killing. I could never imagine what the actual event that happened there was, did the ship crash land on the creature? Is the ship facility an old space pirate facility, and Phantoon chased the pirates out? I just can’t figure it out!
I always assumed that the ship was wrecked by the attack of Phantoon thousands of years ago (the manual states that it’s millenia old), then the pirates managed to bring the ghosts under their control once they colonized Zebes (the manual also states that Mother Brain influences Phantoon’s actions).
