I’m curious to see how the changes to Climate will work.
I have to be honest, I almost never have any issues with it in the MP games I play with my friends when I’m Phonecia.
I’m generally in the top 3 for science so I always hit flood barriers before climate change becomes an issue. Also it’s generally fairly easy to settle on tiles where it isn’t going to flood (granted that may change with the extra 10% incoming). Given that the sea level rises are going to be even slower though, I don’t see it causing me any issues (again, this is limited to me playing against my friends in MP). And the military units are usually the biggest offenders (for us anyway, we rarely build power plants etc because it doesn’t generally feel worth it...), so those being halved feels like it will help a lot.
My only issue with the coast is that it’s quite random. I’ve had some games where it feels pretty underwhelming, and other games where it feels possibly too strong. In my current game, we are in turn 119 and my 6 Cothons are all giving 8 science, 8 gold, 8 production and 2 culture, and my coastal resource tiles are all giving 4 prod, 4 food and 2-4 gold etc. However, this requires a bit of luck with pantheons and city states etc. I wish that some of these bonuses were baked into the core coast, to make a little more consistent.
I suppose though, if climate change really becomes an issue, there is the option to tone it down?
