Is Colosseum working?

[PoweredBySoy]

I built this wonder in a city, but I'm not seeing its amenities effects in a neighboring city-center which is exactly 6 tiles away.

In fact, I'm not even sure I'm seeing the amenities in the home city. I assume this wonder would add 3 amenities under the "buildings" amenities category, correct?

Or am I just not understanding this thing?

Colosseum effects are displayed as Amenities from Entertainment.

Oh, I see what I was doing wrong. I was measuring distance from city-center to city-center, where as the distance from the Colosseum to the neighboring city-center is 7 tiles. Fudge.

I love all the thought needed in city design in this game though.
