does anyone use these civics at all?
1.) Representation - seems useless cause it only gives +3 beakers per specialist and not all cities rely on specialist and considering that later techs are in the thousands i dont see how 3 more beakers would make a difference.
2.) Pacifism - +100% GP would be nice if not everyone is declaring war on you.
3.) Free Religion - it's like being neutral in the game and this will cause one to have not so solid allies and still some enemies
4.) Environmentalism - seems really pointless when other civics can yield more hammer or money
1) Representation? In my early days of Civ4, while playing with a poorly planned economy, I often used this for a while. Either from Pyramids early in the game (this was ok) or once I research the relevant Tech. Once I found the advantages of Financial Trait, I ran exclusively Cottage Economy, and with few specialists, it does not matter a lot, with +3 Science. But, I most often get Happiness from other sources, Hereditary Rule is not civic I use a lot. Hence Representation is the best choice, if only for a while, because even a few Specialists with +3 Science is better than none. I always moved up the ladder, once later Civivs became available.
Recently I've tried Specialist Economy, and have had some good succes with this. And this is where Representation rocks, you'll have an easy time, if you bag the Pyramids, and run Representation from the point where your 3rd city has a Library.
2) Pacifism? In my early Civ days, I didn't like this. However I soon saw the increased number of GP could outweigh running Theocracy for more exp in units. Especially if running Specialist Economy, combined with Philosophical Trait. This steady stream og Great Scientists to settle in your main science city makes or breaks this economy. I only run other civics for a brief time. State Religion if I'm, gunning for Wonder, preferably multiple ones at a time. Or Theorcracy if warmongering.
3) Free Religion? I almost never use this anymore, and then only very, very late in the game, where Monasteries are obsolete, happiness or culture is not a point, where religion does not muck up diplomacy. Few of my games last this long. And - sadly - I don't mean I've won them before then! I mean I've either given up as lost cause, had the game crash or lost interest.
4) Environmentalism? Actually, this would be the only civic I've never, ever used. I think it could be useful, if Health is an issue. If you have few health resources, and have kept your jungle and woods, you could get something out of it. Perhaps coupled with Forest Preserve. But I always chop and use all available terrain. If a few woods stay on, it's because I intend them for Saw Mills.
But I think the system of civics is great. When I first started playing, there were a few Id never touch. later on, as I understood more, I changed my preferences, as I saw how CE thrived. Recently, with SE going, I use completely others.
