I have to agree with those who have the opinion, that bonus ressources are just that, bonus. It gives a better start for fresh cities and is most valuable in the early game. Later in the game, when the number of possible districts increase, CiVI is kind of a puzzle game, so you will probably have to get rid of those ressources anyway. And yeah, it really hurts me to see too, that a lot of preview lets play dont use the harvest function. Harvesting sth for production is nearly giving a free builder in most cases, just for the use of one charge. And if you place a district somewhere where no bonus ressources is placed, you can get rid of another one to push the construction, same for wonders too.
So you always have to decide, what is better. And a lot of bonus ressources need farms or mines anyway, but I have to agree, that cattles and camps seem to be weaker then those. The same question is with lumbermills on hills and maybe on river hills woods too. They can push your production quite a lot, but im still unsure what will be better, chop the forest and put a mine there? How affects the lumbermill the appeal again? Positive or negative? Will it deny the adjacency bonus for the holy site (I think it was unimproved forest, wasnt it?)
But there are still a lot of questions how usefull it will be to keep the bonus ressources or not. Germany's Hanse will require it, if you are not focusing on getting as much as possible adjacency bonus out of districts and especially of commercial hubs (I think it will be common for Germany plays, that you found cities in that way, that you can place 2 ch and 2 hanses in diamond shape next to each other, probably on rivers, to get the best out of those, if there are ressources too and coasts with harbors, even better...)
And last but not least, I have the feeling, that it is not a good decision to settle next to luxury ressources or strategic ressources. Because on those you can place districts and wonders, which will limit yourself in city planning. F.e. settling on a river next to a luxury ressource will deny you a whole tile where you can place an aquaduct during the midgame, if you need the extra housing (even more for Rome) and it will you deny the extra adjacency bonus of the district too, which is at the beginnig the smallest bonus you can get, but if your city grows and you add more and more districts, it will start to matter.
So I have the feeling, that in the long run, most people will settle directly on luxury ressources, to get the amenities and to have the most space avialable for the latter puzzle game.
But yeah, first we have to have the game in our own hands, before we can say what is really good or bad, only 2 weeks, Im counting ...
