i have multiple favorites gen 1, gen 2 then gen 3. Gen 1 because
thats how i started with pokemon and squirtle my favorite starter.
Gen 2 because of feraligator and i already played gen 1 and loved
the game. Gen 3 because i think some of best looking pokemon came
from that gen. Metagross, the starters, rayquaza, seviper, etc
i LOVE unova. i didn't like it much as a kid when i first got it
because of the chunky battle sprites, but it really does have the
deepest and most intriguing plotline, characters, etc. and it added
a ton of new amazing pokemon (and a few of the worst hsbdjs looks
at conkeldurr).
i like a few of them but unova is my favorite. while heartgold was
my first pokemon game and i absoluty loved it, something about
white made me love the pokemon in that generation. i just started
playing white 2, a game i didnt play much of when i got it, and it
has gotten me back into pokemon after kinda growing distant from it
since moon.
