Combi-nations is the latest Corné Van Moorsel game (the designer of Habitats), one of my latest KS backs, and I have received it already. I granted it top priority and it got played immediately.
To be fully honest, setting up the game is a bit of a chore. I am used to games where the set-up is much, much faster, or at least less cumbersome. Here you need to build piles of hex-shaped tiles (that I had sorted out beforehand), which is just boring and tedious. Anyway, once it was all set-up, I was happy to start playing.
The goal of the game is to draft tiles (you can only draft tiles 1-3 spots ahead of your arrow, and the "AI" arrow also drafts tiles and serves no other purpose but that of refreshing the offer a bit). Then you place the tiles on your city (the brownish tiles in the back of the picture). You score points for "big" areas of matching colors, and the color that scores the least scores twice.
15 minutes later, I got 56 points.
This is pretty much what I expected. I find the draft mechanism to be slightly too cumbersome for its impact on the game and I consider getting rid of the AI arrow entirely to make the game smoother.
The set-up and tear-down are clearly an inconvenience. I think a better alternative would be to have dedicated cloth bags for each of the five different shapes and draw from them (as in Alice's Garden). I do have cloth bags, but it would be nice to have the shape symbol imprinted on them. In this way, set-up would become incredibly faster.
My first impression of it is rather good, but I want to see whether the game allows for clever planning (even though my mind set is so inherently tactical that I doubt being able to plan over more than a round or two).
