Japanese gaming publication Famitsu has confirmed that both 3D Puyo Puyo 2 and 3D Power Drift have been confirmed for the Nintendo 3DS. Both games are part of a Japan only retail collection and will no doubt come as a pleasant surprise to fans. Apparently, Maze Walker and Fantasy Zone II are also in the collection. An interesting thing to note is that both of these titles were confirmed in the list that was uncovered via hidden data in 3D Gunstar Heroes.
Japan: 3D Puyo Puyo 2 And 3D Power Drift Confirmed For Nintendo 3DS

What the hell even is this?!
If you’re asking what Puyo Puyo 2 (Tsu) is, then it’s perhaps the best version of the best competitive puzzle series of all time. Puyo Puyo Tsu is like the puzzle game equivalent of Third Strike.
Oh God please bring 3D Puyo Puyo Tsu here
Please
Pleeeeease
