What did you think of the additions made to Gardevoir in Generation VI?
I think Alpha Sapphire was the first time that I featured Gardevoir in my party, and a large reason for that was both the addition of the Fairy typing, and its added Mega Evolution. While I'm not saying I wouldn't have used it if remained unchanged, I definitely think these additions brought up its value in my eyes.
Gardevoir has legs under its dress...so, is the dress a part of its body, or like clothing? Similarly, as its body is white, are its green sleeves a costume, or a part of the Pokemon?
There are a lot of Pokemon in a similar conundrum (Hitmonchan, Gothitelle, Machoke/Machamp, Sawk/Throh) where they may be wearing clothes, but you can't be 100% sure. I'll always treat what they're wearing as clothes though, as it's a bit weird to think of them as skin or fur or something similar.
How many times did Youngster Joey call you?
Way too many times in Gold, though I don't remember him calling me a lot in HeartGold (maybe I never added him to my Pokegear?). Eventually I had to make room for other trainers so he was one of the first to go, but maybe he wasn't as bad as I remember.
Do you find Rattata to be particularly annoying when compared to other common early game Normal-type Pokemon?
While I don't particularly care for Rattata, I preferred it over both Bunnelby and Bidoof (though the latter was good if you needed an HM slave early on).
