Some games were bought by me, and some came from my brother.
Jupiter Strike (PS1): a Starfox knockoff with a slow moving ship, weak weapons, and a boss at the second level that is impossible to beat (unless you have a GameShark). There are no continues, so Game Over means going all the way back to level 1.
Mansion of Hidden Souls (Saturn): A game with people as butterflies, a decent story, nice music, and...you can easily beat it in under 2 hours. It's so short.
Castlevania Adventure (Game Boy): no subweapons, sluggish gameplay, a falling platform in the second level that will kill you unless you make perfectly (and I mean PERFECTLY within 0.000001 second) timed button presses to jump over it.
Celebrity Deathmatch (PS2): a game that seemed like it had potential, but you have minimal moves, a pathetic AI, and it only runs on comedic lines and gets boring after 20 minutes.
Soul Calibur 3 (PS2): a good game, but I regret it because of the File Corruption problem. Bugs. At least it didn't fry my memory cards.
