I've been playing since I was 4 😂😂
Personally, I recommend you getting Pokemon HeartGold/Soulsilver and B2/W2. They are both phenomenal games, with HG/SS known for its large play through and B2/W2 known for the story and post-game features.
Then again, you can't go wrong with any game. My least favorite(XY) would still be considered good, perhaps a 8ish rating. The games consistently improve, with the battle system being extremely solid.
I just hope you don't become attached to Pokemon Go. It's very shallow and only fun for like 5 minutes. Each pokemon game offers hours of gameplay.
