Even though I do really like the Sims 4, the price of all the DLC and stuff you need to buy to get the full experience and the fact that you have to have an Origin account linked to your copy of the game (at least this last one is why my sister says I can't play the Sims 4 on my computer) drops it out of being my fav between these 3. Tbh Pokemon is my all time favorite game series but I really didn't like SuMo. I could explain why but that would make this post far too long, so in the end ACNL gets my vote. Now if you would've said Pokemon XY/ORAS than this would be a completely different story as I love those way too much, especially XY.
