once i came across that one cave in the middle of the ocean (i think lugias?) that needed to be lit up with flash. i decided to go through anyways and got so far in. but i decided i want to leave, i was so far in that i couldn't even figure out how to get out anymore i just started a new file.
Also i didn't know that healing at the pokecenter regained move PP. my ho-oh's sacred fire ran out so i replaced it with strength -_-. There were no move-remember guys back then were there?
I nicknamed my Piplup in Diamond, well, Piplup because the whole upper-case only thing bugged me. Only after evolving it did I realize that in Diamond a "PIPLUP" nicknamed Piplup will evolve into a "PRINPLUP" named Piplup.
Unfortunately I had also caught some other Pokemon I had intended to use at this point, most of whom suffered the same fate.
Having just gotten the game and not wanting to start over, I spent the first part of the game very eagerly awaiting the name rater while my team's names were stuck as their base forms. I don't remember how long it was (where is the name rater in Sinnoh?), but ****, I felt stupid.
I summoned a baby to attract a lion. It didn't seem to work, so I tried a delicious baby. Regular baby ATE delicious baby. Horror....horror.~Gameplayingperson
