Yeah, that per-city tourism penalty threw me off for a long time because, for example, Arenas give +2
, but once I had built Arenas in every city of my 10+ city empire I didn't have 20+
per turn on the UI. The reason is because even if you have one city in addition to your Capital, the per-city tourism penalty rounds 2
down to 1
in EVERY CITY. So even if you build 10 Arenas, that will never net you 20
because each city gets rounded down to 1
. In the example above the 3
from the Holy Site gets rounded down to 2
. Or, if you manage to build two 1
Wonders in your Capital your tourism per turn will still be listed as 1
in the UI because it gets rounded down. This matters less and less over time as your Capital and other cities generate more Tourism, but early in the game it can create situations where you are losing 30-50% of your tourism output due to the game rounding down in each city.
