Favorite Official Touhou Game?

and why?

Anything released by ZUN with a numbered title can count, so the Impossible Spell Card-likes or the fighting games are fair game.

For me I'd say either Imperishable Night because it just feels good to play or Legacy of Lunatic Kingdom because it's checkpoint mode made it both more forgiving and also more challenging.

Impossible Spell Card!

Super fun and neat. Lots to love about the gameplay and the style. My favorite mainline game is LoLK. I like Pointdevice mode.
