Okay, I think I have a plan now 
Both Caverna and Agricola are on BGA. My friend who is just beating me again on 7 Wonders Duel
(:
me: disgressing
I am not convinced that the 2nd expansion with the parliament which I am now playing for the first time, is something the game needed, the first expansion is really nice but also not necessary, base game has enough meat to chew on for a while
)
seems to have some brainspace currently (he’s doing AoC), I might convince him that we learn them both and play on our own time.
I am a huge Rosenberg fan. I currently own with no intention to sell (possibly unintenionally listed in order of how much I enjoy them):
- Nusfjord
- Sagani
- Bohnanza
- AFFO w/Expansion
- Oranienburger Kanal
- Fairy Trails
Possibly not forever but currently not even close to the sell-pile:
- Fields of Arle w/Expansion
- Hallertau
(at 8 games that’s more than half as much as I have Knizia’s and the same number as Cathala’s. One might think I have a a lopsided collection)
Additionally I have played and enjoyed apps of
- Cottage Guarden (I should have bought it at SPIEL but it was sold before I ever found it that year and then I had the app and now that isn’t enough and it’s OOP but I am not desperate enough to go looking for a copy)
- Indian Summer
- Patchwork
- Le Havre (not recently, I barely remember the game)
- 2 Player Agricola
- Agricola (also played not digitally sometime in the late 00s, also one of my first solos I ever attempted and I never won)
So there is some history there and always space for Rosenberg games on my shelves.
All that said, I think BGA first. Neither Agricola nor Caverna is going OOP anytime soon.
