A) I got a GB Color and Pokemon Silver when I was eight years old. I missed Gen I because little kid me was a dirtbag hipster who didn't want to be into Pokemon because everybody else already liked it. My tune changed when one of my friends whipped out a poster with all 151 pokes on it and I laid eyes on Rapidash, and dude? Flaming unicorn? METAL. I really got into it after that, watching the show and collecting the cards and whatnot (even subscribed to Beckett Pokemon Collecter, remember that?), but my parents were slow to let me actually get a Gameboy since they didn't want me indoors all day playing videogames.
I remember debating carefully over whether I wanted Gold or Silver more. I think I went with Silver because Lugia learned water moves, so could beat Ho-Oh. Also, Vulpix, my favorite Pokemon at the time, was a version exclusive. When I finally got it, I played the ever-loving crap out of it, until I had well over 300 hours on the timer, a complete Pokedex, and a full party of level 100s. Originally, I intended to keep that save file alive for posterity, but one of my brother'Sis friends saved over it. That was the saddest day ever.
B) While Silver was my first and I still like it a lot, it is no longer my favorite. Crystal was objectively better (and let you play as a girl!) and had those really cool animated sprites and stuff. My favorite now is X/Y, mostly because it's so accessible. Before, I could never hope to get into competitive battling, but now it's much easier to breed, trade, and battle online with your pokes. The Johto region and Gen II Pokemon are still my favorites, tho :)
C) Oh jeez, the derp was strong with me back in the day. First of all, totally named my rival ??? because I thought the cop would know if I lied and arrest me. Secondly, had a strategy guide that I followed to the letter even though, looking back, it was objectively wrong in some places. Third, I think I got lost over by the Whirl Islands and cried about it (did the same thing in a cave, too). Finally, I thought I was cool for mastering the cloning glitch and wound up accidentally deleting my friend's Espeon (we didn't stay friends after that...)
Good times, man.
