Is this gamey?

[Stone Mill]

As pointed out earlier, the benefits of this move may be overestimated. The bonus produced by the arrangement is a drop in the ocean, and the empire giving the planet has foregone a chunk of resources.

It may be frustrating for you, but it is not gamey. I have seen this move many times, and mostly, I think that it is to keep a player in the game so they can continue to have some kind of impact for a bit.

For all intent and puropse, they aren't able to really do much with one planet, so it does not bother me at all. Their expansion will be at the cost of their allies. There is only so much space in the quadrant, and you have made progress in a forward direction.
