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
Oh, I see, I particularly like the pokemon fan made ones more, I think they have better design and story than the "official" games.
Pokemon reloaded is one of them, although it has many very good particularities, like the music and the way the battles are developed, since it is very similar to the battles in the anime, the pokemon can run to avoid attacks and you control it, you decide at what moment to use the moves, etc.
Since you have recommended Daybreak, I recommend Reloaded.
Definitely giving this one a try after I clear Reborn. Still more than 40h of Gameplay left though, it's gonna take a while haha
