Okay okay okay, this is a super serious topic. If you are a big fan of Pokemon, you will know how much the games can differ ._.!
My personal favorite is, and always will be Emerald. I do like the newer ones, like X and Y, but I find that I much prefer the feel of the older
Pokemon games. Also, Emerald also has the best story line in my opinion, paired with amazing starters.
Let me know your opinion ;P
