ayed around with some test games last night to check out possibility of getting a religion and found a couple of points. Research fishing first. Fishing takes 8 turns to research with the type of start we have. Being able to access the costal and lake squares then allow you to shave off 5 turns in researching Polytheism second. This makes fishing only cost 3 tech turns and they occur in a game time where the other civ's do not seem to found a religion (unless they pop a hut). Look at the top 5 cities list before founding your first city. If I remember from GOTM3 replay, the other cities are founded before yours so I guess they will already be up and you can get a peak of 5 of the 6 civs, if 2 have mysticism or 1 religion and Munsa (he seems to beeline for religion in most of the tests I did) then do not go for a religion, you are very unlikely to get it. If 1 has mysticism or Munsa is in the game then you are likely, if none do you are in very good shape. Mystical civs tend to get there religion between 3640 and 3560, which means that you can switch out of polytheism if it gets researched here with just a small tech delay. the biggest wildcard seems to be Munsa who a couple of times in my tests founded Hinduism around 3400-3200. Which would not allow a swtich. Also check the top 5 cities right after fishing as they may change and reveal another group. With switching to water tiles you should be able to found Hindu around 3200, but you need to remember to switch research to 90% when fishing is found. You could do better if a hut is popped and you can stay at 100%. My summery of this is that going poly or meditation first is the wrong choice, start with fishing and do not go for religion if two religion oriented civs (including Munsa) are known to be in the game.
