da fuq is this, u gotta know math to play pokemon now?
BACK TO THE BLUE AND RED DAYS
This was back in Blue and Red too, that game was way ahead of it's time, or too behind, considering how dumbed down games are these days
There were hidden values every time you battle a pokemon and you would gain EVs it wasn't till later people found out how to properly min max the game. So if you didn't know everytime you battle a pidgey you would gain 1 speed EV and every 4 EV is one stat point, so to max a stat you need 252 which means you need to fight pidgey 252 times no more no less (you had a +/- 2 points as leeway)
They made generation VI (x & y) very easy, as you can do the mini game to EV train before you had to do the math on paper and if you miscounted you were pretty ****ed, they also adjusted the max value for EVs too so there is zero counting unless you want a specific HP amount for lets say a snorlax
What I was doing in the picture was rolling for starting stats, you would do the same in all the older ones too, min maxing is where the fun is
