So, I saw Jotari's Fire Emblem topic and thought a pokemon gen version of it should be interesting.
Gen 1
Like: It started it all. Kanto is an amazing place.
Dislike: wow I actually had trouble thinking about this one. I'm going to say no way to breed pokemon haha
Gen 2
Like: The starters. The Totodile and Cyndaquil lines are just fantastic.
Dislike: Johto has terrible balance. Few gen 2 pokemon are caughtable there, which is stupid.
Gen 3
Like: Hoenn. I absolutely love Hoenn. It's just a fantastic, diverse region. I could never get bored of gen3!Hoenn
Dislike: Okay, this is even harder than Gen 1's haha. I guess I'll go with how tedius EV training was.
Gen 4
Like: Physical/Special split
Dislike: IT'S SO SLOWWWW. Diamond/Pearl is the Path of Radiance of pokemon haha
Gen 5
Like: Dream World abilities changed the competitive game a lot. And for better.
Dislike: Unova is too linear.
Gen 6
Like: How many pokemon kalos had. It was amazing being able to choose between more than 400!
Dislike: I was hugely disappointed by ORAS and thought its version of Hoenn was soulless compared to RSE's
