Got some play-testing done with the test version. I've got a few things on my list:
1. Culture to tourism conversion ratio definitely isn't 20%. When I finished building the Mausoleum of Halicarnassus I had +2 culture per turn, but turned out I got +10 tourism with all known civs. Later on I got about +8 tourism for completing a city quest while having +6 culture per turn. At some point I got +81 tourism for completing two CS quests simultaneously while generating +13 culture per turn. It seems that the tourism gains right now aren't following any specific rules or conversion ratios.
2. I noticed that free great people that are obtained by the Mayan UA don't generate instant tourism. That's fine if it's intentional. However, after completing two or three cycles, great people born in a natural way stopped generating instant tourism, too. Neither my first great prophet, nor a naturally born great merchant as well as writer raised the tourism count (all were born after the second Mayan calendar cycle, I think). Not sure if the Mayan UA is to blame, but I'd call it.
3. Player is mostly oblivious to tourism level fluctuations. This is more of a UI issue that stems from the vanilla UI design that's associated with tourism. It's really clunky - I've always hated how you could easily see how much influence a certain civ had
over others, but couldn't see how much a certain civ was already influenced
by others. For example, if I wanted to see who had the most influence on me, I'd have to click through every civ in the 'Cultural Influence' (or whatever it's called) window to get that information. There's no easy way of finding out who's exotic/familiar/influential etc.
over you until ideologies kick in.
Here's where I'm leading this to: could we possibly have a popup that notifies you when somebody has achieved/surpassed one of the stages of cultural influence over you? Similar to the notifications that inform you about your cities' spy potentials when they hit a high level of vulnerability.
Also, is it possible to have these instant lump amounts of tourism show up as popup yields over the player's capital? Similar to how the amount of culture gained per researched technology if Progress is adopted is briefly shown (as well as many, if not all, other instant yields per something effects). Right now it is a chore to go into the culture/tourism overview to see how much tourism you gained every time you build a wonder/complete a CS quest/generate a GP.
I'm sorry if this isn't your area, Gazebo, as you generally don't do UI work. It would be naive of me to think that these changes are easily implementable.
Gameplay feedback aside now:
Ultimately, I probably should not have released a test version, because it seems there's a misconception floating about that an untested set of values (i.e. values I did not stress test with the AI) reflect some kind of finished or reliable product. Generally, this kind of version never sees the light of day.
As long as there's somebody willing to help with testing some of the trickier things out, there's really no reason not to release a test version. In the end, you did all you could to indicate that it's not actually an official, polished version, but rather a test one.
