Gen 2 (Crystal version in particular) brought many new things we now take for granted in pokemon games.
I can get why you like the rest but..Boldore? xD
It's not really about them being Legendary. I just like their desings. Volcarona's unique typing, kyurem's looks and a 3 headed dragon, win! :3
Oh I see, free dex entries ftw! :3
Quite the unusual team. And such a high leveled Farfetch'd XD
Yea some pokes got nerfed ._.
And you're welcome, it's always useful to know the changes in a game :3
Edit!:
Oh and the Wifi battle thing is pretty useful.
(Don't know if it's the same in X/Y) But if you go into a wifi online battle with someone you can choose the level you want to fight with (lv 50 or lv 100) and when you battle all your pokes are lv 100 for the fight. And doing that with hatched pokemon will gives you 100% accurate IV's if you calculate them.
