Third generation.
Nobody appreciates it enough. Everyone is always: "1st/2nd GEN!!!1!!1! :DDDDDDD"
Please, R/S/E were good games. Hoenn was both creative and functional. The pokemon were so original, designs you just couldn't compare to the meager pokemon of generation 2 or 1. Even now,I believe they are far superior to generation 4, as well.
Every time I go back to play third gen. I find a new pokemon I adore.
...Castform, Swalot, Regice, Breloom, Grumpig, Armaldo...
I don't find that with the other generations. When I'm playing the other gens. I always battle with the same team.
and....
They are infecting your remakes! Go catch your Kyogres and Groudons, 2nd generation fans! GO, GO, GO!
