i do like the idea of the beauty stat; thats what i loved about milotic, the hard work made it that much more rewarding :D
That would make a lot of sense if it was the beauty stat that makes it evolve.. Overall I'd like more Pokemon that you have to use the various contest stats to evolve. I like unique evolving Pokemon that doesn't require trading to evolve.
There is for one of the games.. I forget which one, I never use it though. :/ I prefer playing the way the game was originally intended. Somewhat easy, and a little bit hard.
I believe that there is a hard mode in B2/W2, though I can't say I know quite how it differs from the standard fare. I'd imagine that enemy Pokemon are on an all-around higher level. I wonder if the difficulty of the game could affect one's ability to train post-game e.g. higher level elite four members allowing for faster training.
In all likelihood, you just read a clunky wall of text. There's no need for me to make you read even more in my signature.
