I wonder if the reason some of you think it's so easy is because you're just very good/experienced with the game. R&F has been out for quite a while now, I guess anyone who's been playing it since release will have nailed down the routines to get era points.
For me, I only played vanilla for a few games before losing interest (I didnt like vanilla so much). Then I picked the game up again recently, getting GS and R&F together. I probably have played less than 10 full games with the expansions and I still struggle to get era points. I'd probably do better if I looked at the list of ways to score points but when I'm playing I just want to keep the flow going. Some important sources of era points are eays to remember like unique units or buildings, circumnavigation, first unit of each strategic resource, etc. Others not so much. But even then it's not something that's constantly on my mind, at first I used to get to the end of an era and then think "oh no, I forgot about era points". But i'm getting better at it with every game.
Still though, I dont like to play my game like a to-do list chasing after eurekas, inspirations, and era points. Not that I dont try to get them, of course I do, but I dislike going out of my way for them if it's not what I want to do, even if in the long run I might be better off getting x or y eureka/bonus/era point. It would just detract from my enjoyment to play the game too formulaicly.
I'd say I get an unintentional dark age in about half my games, more so at immortal or deity difficulties. The other thing I noticed is that it's a bit harder to get golden ages if I'm not aggressive, especially if I start with several nearby neighbors. But sometimes golden ages do have a domino effect of one leading to the other. Heroic ages are just awesome.
Don't worry about ages.
I personally only take very careful on era points when
1. I have a ton of faith, under such circumstances I have to get to monumentality to make full use of the faith. However if the faith comes from Holy Sites, monasticism+Jesuit is better. So I wish to get into either dark or golden age, but not normal age.
2. I have a ton of Harbors, free inquiry gives a lot of science so I must try my best for a golden age.
Otherwise you don't need to care. Being normal or dark will not hurt you since even if you get to golden there's no severe bonuses. Twilight Valor on dark age is strong but not game-changing. Same for the district+1 culture golden age.
