Gen 1...
I played the three games when I was young. Also managed to play a horribly-translated green version. >.>
But anyway, my first game ever was the first gen, and it was PKMN Blue version. I lost that game after I threw it like a boomerang outside of our house, and never found it again. xD
I then got Red, but then I gave it to my brother as I got Yellow. :3
Gen 2...
I already invented the name "Jagold" as a character of my written stories during high school, so I obviously got the Gold version. My bro played Silver and we kept on having battles and trading and battles. Ah, good ol' memories. :3
I borrowed Crystal from a friend, but somehow, that game didn't have the "feel" to it, so I didn't bother to finish it. =/
Gen 3...
I first got PKMN Ruby from someone who was selling his GBA and a few games (Ruby included) to my dad. He bought it and I played the game.
Unfortunately, the battery was already dead, so I couldn't save.
Fortunately though, that was when my brother discovered ROMs and Emulators. So we played the game on my father's laptop back then.
We wanted to play the game at the same time, but we couldn't, until my bro made some tweaks on Virtual Boy Advance that made the window not pause when inactive. So, three pairs of hands on the laptop keyboard, all playing Ruby and Sapphire, and then the three of us played Emerald together. :P
I still had my GBA back then when my friend suddenly let me borrow his LeafGreen cartridge for reasons I have already forgotten. Anyway, that was the first game ever that I found and caught a random shiny on Route 1; a Pidgey!
...unfortunately, he started a New Game as soon as I returned the game 'cause he didn't like the name I gave to the player. =/
For PMD, we played the Red Mystery Dungeon. :3 Damn, that game really made us go teary eyed. <3
Gen 4...
Despite the availability of emulators and ROMs, this generation didn't appeal to me. Platinum almost did, where Giratina and Shaymin suddenly became my two newest favorite legendaries, but I still couldn't put myself to play it. =/
Though I enjoyed watching my brother play Platinum. And boy, Cynthia was a very tough champion. o.o
None of my brothers and I played the Gen 2 remakes though. I don't really know why.
We wanted to play it, but I guess it didn't appeal to us as much as I would have thought it would. =/
And oh, we also played Explorers of Time, but I didn't finish it and went to play Explorers of the Sky instead. <3
Oh god, the feels... <3
Gen 5...
Never played the "real" B/W version though. I played a hacked one called "Blaze Black" while my two other brothers played "Volt White".
I didn't play B2/W2 versions, but I enjoyed watching my younger play the game. :3
Gen 6...
Gen 3 was the last gen where I actually owned both a handheld and a cartridge for the PKMN franchise. So buying a 3ds and PKMN X felt really, really...weird.
I was sad that I spent so much money on these things, but I also felt...happy. Happy that, finally, I'm back in the world on PKMN.
Sure, there are emulators and ROMs out there, but nothing beats a real game that you can carry and hold and be proud of.
Anyway, I chose X because Xerneas looked..."meh"-ish. Yveltal is the cool one, but Xerneas being the PKMN of life made me appreciate the legendary, and made me love it. :3
