I didn't have fun with Zelda II. I played it at my cousins' house and died more times than I could count on all of our fingers and toes together. v.v
There's this part in Xenogears, in the Tower of Something or Other, I think. You have to jump and seesaw and do three backflips counter-clockwise while wearing a tutu to get past the level. My mom had to get a memory card from a friend past that point. I was like.. 6 or 7 back then, so I'm sure it's easier now. My mom fails at platforming and was the only one playing it, so I just remember it being hard.
Megaman. The first one. They wanted me to die. The game developers -wanted- me to die. Arcade games are like that.
Illusion of Gaia. That game got CRAZY HARD. It was fine, maybe even a little easy (except for the first boss). Then you meet the lovely vampire couple Jack and Sylvana. They killed me so many times and then ate my save file after I finally beat them. ;-; I've only finished that game on an emu with cheats.
*cringe* Same here. I hate that game. The first part of that very level is fun, but that boss gets me down in 2 seconds flat, with me flailing and desperately trying to attack all the way down.
