For Each Previous Generation...

[Dragon]

...What was the most memorable, or favorite thing about it? Remember! Only Gens 1-6 as they are featured here!

I'll give you my impressions, for example:

Gen 1: The GHOST upon the pokemon tower. D:
Gen 2: Goldenrod City and Whitney! I actually had a blast trying to figure out ways to defeat her.
Gen 3: Milotic! That's where it became my favourite pokemon.
Gen 4: Remember the powder snow that sometimes dropped in Snowpoint City? That was really beautiful.
Gen 5: The battle against N at the end; that was actually epic!
Gen 6: Actually, for me it's the Gym music! Loved how steady yet steadfast it was.

Gen 4: Distortion World! :D
Gen 5: Skyarrow Bridge and the soundtrack (fave gen)

Gen 1: Pikachu's various designs, such as the fat pikachu in red and blue, and the skinny pikachu in yellow...along with the blue eyed pikachu~
Gen 2: SUICUNE!
Gen 3: Pokeblocks being really cool
Gen 4: Polishing your badge
Gen 5: Zorua
Gen 6: Pokemon Amie, having the ability to pet and feed your pokemon made me feel as if I truly were connecting with them.

Gen 1: Probably boarding the S.S. Anne. Seeing it sail off is the first time I can recall feeling any kind of emotion while playing a game.
Gen 2: The iconic showdown with Red of course.
Gen 3: R/S/E still have my favorite maps to explore in any Pokemon game.
Gen 4: The Pokemon follow feature in HG/SS.
Gen 5: B/W's story.
Gen 6: The transition to 3D. Visually the games are great and I think the chibi trainer models are kinda charming.

gen I: i made my babysitter mad bc i went into pokemon tower and started screaming out loud when the ghost showed up and i couldn't fight it. i thought i was going to die. lmfao
gen II: idk why but when i think of gen II, my first thought is always of me standing by my front door waiting on the bus and playing silver in a hurry bc i couldn't take the game w me to school and i had a furret w ice punch. his name was tinnerz. he was good.
gen III: the Whole Game lol. i remember taking the guide book with me to my summer day camp thing bc i was stuck on the last gym puzzle and my friend figured it out and wrote it so hard into my guide book that it bled through the pages and he was using a pencil jfadlksf
gen IV: i had a really shitty team in pearl and cyrus kept beating my ass, but my diamond team (i bought them the day of release and was playing them side by side i should mention) was kicking ass and idk why bc that team was full of basic first route bitches. idk what i was doing.
gen V: ah.......the first petilil spotting........... also i did a lot of RNG abuse dskjfalds so i think abt shinies...
gen VI: nothing......really stands out to me??? except the gym leader theme?? like every time i think about XY i think of the first gym battle starting for some reason. it's not memorable, i guess i just was not excepting That music coming out of That battle

i think i did this wrong but oh well??

Gen 1: Catching my first Pokémon - female Nidoran and taking on Brock with her.
Gen 2: The part up to the Goldenrod City has unique atmosphere to it that I always loved and makes me feeling nostalgic every time I'm in this part, even in the remakes.
Gen 3: I had 0 knowledge about 3rd generation at the time of playing Sapphire, so there are more things - asking my mum which starter she likes the most and choosing it, going through Route 119 and encountering Tropius for the first time and finally restarting the whole thing after loosing to E4, because I didn't want to train new team.
Gen 4: I've never really played Sinnoh games aside from doing challenges on them, but battle with Cynthia is my favourite.
Gen 5: Music. I've started listening to Pokémon music more with this generation and I love it.
Gen 6: These games looks beautiful on 3DS and have the best atmosphere from all the games.
