Which games did you (have to) sell and want to REacquire someday?

I've been making up for overspending last year on this hobby by selling games this year, so I've let go of a lot of darlings that I'll someday get back.

I've got two:

Inis + Seasons - Such a robust, clever, weird and gorgeous game. I'd perhaps keep this if I could keep only one midweight area control game.

Spirit Island w/ all gameplay expansions - My favorite solo game, but wasn't getting played due to lack of play space.

Oh, and how could I forget Concordia? Oddy enough I don't feel so bad about this one - but only because I prefer my beloved Hansa Teutonica, and they'd compete somewhat.
I begrudgingly let go of Inis because El Grande and The King Is Dead were smarter yet.
