I don't think I watched nearly that many anime shows back in the day, haha. Though Pokemon, some bits of Digimon, and Yu-Gi-Oh! were definitely on the list.
I'd say that Fairy Tail was the first anime I watched subbed, and the first anime I was really into. Like, REALLY into. I practically memorized almost all of the original 175 episodes, fell in love with the OST, and was just enamoured with every single character (I could name 25 off the top of my head right now if I wanted to, lol).
Nowadays, rewatching those episodes makes me feel strange. I get this sense of nostalgia while at the same time this sense of awkwardness the more aware I become of the series' MANY flaws and lackluster animation compared to the other shows I've watched. It makes me appreciate just how much my taste has "grown", per say.
Still, I'll always hold Fairy Tail in a special place in my heart. I'm just glad I really started there and not with SAO, haha.
