I got stuck on my third playthrough on Tales of Symphonia well over a year ago about halfway...
Because I had tried everything I could possibly think of, and the walkthroughs I was looking at weren't helping... It was even more frustrating since I'd beaten it twice before, and I had no problems then.
I finally came back to it a couple months ago and easily got unstuck, and realized what I had missed was incredibly obvious...
Which made it really frustrating. I hated the Meltokio sewers, they were annoying.
Also, I've been stuck on Donkey Kong 64 for YEARS because the last golden banana I needed was from the Mario game, and I can not beat that. Period. D:<
So I've given up on beating it on that file...
