This is a fan made Pokemon game and has Pokemon from lots of different generations. This one has a dark plot, it's +18 haha.
I've played White too, decent game butbnot one of my favourites.
You should play pokemon daybreak, really enjoyed it. Fan made so lots of different gen Pokemon, difficult and great story
