Snap is the only option for the spin-offs. Nothing comes close.

Not gonna lie, I'm torn between the trading card game, pinball, and snap.

My first instinct was to go with Snap but if we're including the Colosseum games in the Stadium series then those probably push it to the top. For all the problems it had, Colosseum was an incredibly interesting branch for the series that I wish had been followed up more on.

Snap, and it's not even close for me. I love TCG and also enjoyed GO a lot as a nostalgic experience, but Snap is such a different thing, immensely fun, and I played it in the year of our lord 2016.

If it was a longer game, I'd go with SNAP, but the TCG is so much better than it has any right to be.

Ah, I forgot Detective Pikachu. Sry.

Both versions of Pokémon pinball were incredible. I’ve tried to visit the TGC GBC game a few times in the past few years, but it’s a pretty slow affair. I’d love a proper update to it, but we don’t get decent card games on platforms other than PC or mobile devices nowadays.

Out of what's here, the Trading Card Game was brilliant (Imakuni?'s theme still slaps), but my favourite was Pokemon Conquest on the DS.

Nobunaga's Ambition, but Pokémon. What's not to love?

@jayc4life: hmm, interesting. Crossovers are unique beasts but it should've been squeezed in here.
