@A that's really hard to answer since 
are all in the same gen
@g yeah, just like the "choose one fave for each type thing" is a challenge because people often like one type more, it's something that makes people have to think about groups of Pokémon they usually don't care about :D
a lot of my faves are in Gen II, so I totally get you!
