The only Pokemon game of any kind that I've ever played was Puzzle League but it's one of the best games I've ever played, PERIOD.

The Mystery Dungeon series is my favorite Pokemon spin-off, with Explorers of Sky being my favorite Pokemon Mystery Dungeon game.

Wow this thread made me realize Battle Revolution and Super Mystery Dungeon are literally the only Pokemon spin-offs I've played. So yeah, don't have a choice but to vote Mystery Dungeon!

Pokémon Colosseum although Mystery Dungeon comes really close.

Pokémon XD is my favorite, its the only one that feels like a mainline game at all. Pokémon Trading Card Game is my second favorite.

Pokemon Snap is a cool spinoff for sure!

Mystery Dungeon. Especially Sky.

Really looking forward to Pokken disappointing me with its lack of content despite the huge potential and solid gameplay, though. Can't wait for that.

EDIT: Snap is barely even a good mini-game. People need to stop with that.

Mystery Dungeon and Picross. Specially a fan of Super Mystery Dungeon and Explorers of Sky.

Two things:

1. You think Stadium was limited, but you like Snap? Come on. Snap didn't even have all the original 151 Pokemon.

2. You were supposed to use your own Pokemon from the GB games. You didn't have to pick the preset teams and moves.

Yeah, I remember using my Poké Blue pokémon. But still, you needed the little thing you attached to the controler if I remember correctly. The game by itself is nothing great. All you could do is battle, it got old so fast.

As for snap being limited, I understand today as an adult how short it was. But at the time, before the internet and when we were kids (atleast I was at the time), the game felt like it was filled with secret. I remember talking to my friends about secrets that felt like myths at the time untill you tried it. Like how you could take pictures of Charizard, Gyarados and Dragonite. So Snap had a sense of adventure and mystery to it, wich was totaly absent from Stadium since stadium was basicaly a combat simulator.
