I remember Ultimecia. I was 13 yo when I played FFVIII. I wiped more than 100 times, and when I finally defeated her, I screamed like crazy and I was trembling.
I remember Adel, the boss who slowly killed Rinoa. I wiped 50 times before I tried Irvine's special abilities, and destroyed her in 2 mins. I was extremely happy.
I remember Psycho Mantis, and the intelligence and ingenuity required to beat him in Metal Gear Solid. My head hurted when I figured it out.
I remember the puzzles of Silent Hill 1,2,3.
I remember the wipefest that was the original Forbidden Siren.
Those were the days, when videogames were actually challenging and required mental capacity and ingenuity to defeat.
Nowadays, even with some medium difficulty battle added to a faceroll game, snowflakes complain and whine for nerf.
Grow a pair, learn the fight, wipe endlessly and when you finally beat it, you will be way more happy than facerolling through it.
