This ^^I always thought gen 3 looked like eye candy. Hoenn is very colorful.
I enjoyed gen 1&2 (gen 2 is my favorite across all gens) and hated gen 3. For me it was the poor graphics. However I've gotten over that. But yeah gen 3 came out during a time when the original fans were starting high school and pkmn was suddenly deemed un-cool. Before then people would sneak the games into school and trade cards behind teachers backs.
It'd probably gain more popularity if there were R/S/E remakes. Not for the sake of having the remakes, but because the remakes would be available on a DS gamecard like how you can with the other generations. I loved playing Sapphire version though when it came out.
Completely opposite, I'd love it if the newer games were suitable for GBA.
