I literally have no recollection of Endeavor. After writing those words I did search for it in my blog and found a quote:

I’ve now played Endeavour three times. It’s fine, respectable, and I imagine it will be forgotten in a year or two. — Me

So, I’m pleased that my assessment was correct. One point to Ravenclaw! Even looking at the pictures on BGG, I couldn’t tell you the first thing about the game. And — since I was aware that Endeavor had left no mark — I was not particularly interested in trying Endeavor: Deep Sea. But it has been repeatedly getting to the table instead of dying out (like the flash in the pan I suspected it was), so I tried it.

And I’ve got to admit, there a plenty of reasonable ideas. You have simplified tech tracks you want to advance (to get a better selection of workers, more worker discs, and movement for your subs) and you both build the board and fill in the boards. So there is a feeling of growth (as you get more worker types and spots on the board) and shrinking (as you spend your worker discs to claims spots on the board, removing both the disc and the spot). The central board is where players conflict, but a lot of the game is “heads down” managing your tech/discs/workers.

All of which is to say that Endeavour Deep Sea is fine, and respectable. I suspect I won’t forget it quite as quickly (since I’ve had some “Endeavor reinforcement.”) There is nothing “wrong” with it, but it has enough of a point-salad-y scoring that means there is no spark of excitement where it haunts my thoughts.

Rating — Indifferent.
