I made a typo. I actually meant ALL pokemon games were boring when it came to leveling pokemon from the 60s and up because most trainers wouldn’t have anything higher than 55 so in the long run I think you would enjoy black more than white but if you can and your a hardcore pokemon gamer then just get both, so you can get everything for 100% completion otherwise I would get black 2.

From what I read in black you get an ingame item which raises the level of opposing trainers pokemon which is nice since in the previous game killing wild pokemon was chore and boring. White however does the opposite and lowers difficulty.
