About the forests i would like to add that you can cut forests not only outside your city radius, but even outside your cultural borders. If you cut forests 1 tile outside your cultural borders, you get the full shields. If you cut them further than 1 tile from your cultural borders, the rewards from teh cut are reduced by 5 shields per tile that you are further away from the border.
Religion i have also tried. I don't know at what level the religion fanatics are playing, but i found on monarch and emperor that the AI simply researches faster than i and even if budhism is the very first tech i research, there is a extremely big chance that the AI will get it before you. Hinduism seems a little less favored by the AI, but still it is very often researched faster than i can get it.
Using a lake tile could help a little bit by increasing your research from 9 to 10. I have not tried it myself though. I think it requires fishing to use the tile and still then, it will reduce your research only a little. It will only help for those levels where the AI has a very small advantage and just barely outresearches you. I am learning this game to prepare for deity of course. (unless i decide the game really sucks and put it away within the next few weeks) On deity, a lake won't make you get the religions either.
The most important reason i would like to have a religion is the culture. It is very nice to have SOMETHING providing culture in every city. So nice that i'd almost call it a must have. Luckilly, there are many options to get this. Religion is one option, being creative is another, and stonehenge is a third.
I just explained why i dislike early religions; the risk of being beaten to it and pretty much wasting your first 10 turns of research.
The creative trait is usefull for this, but i prefer to have the industrious trait. Industrious makes it very easy to build stonehenge, This one makes sure you have that culture in early game and it can produce a great person. This great person can then be used to get theocracy i believe, providing us with a later religion.
Of course, creative is nice. And there are many more nice traits. comparing all the civs however, i really liked the chinese because everything is good about them. They have the strongest trait with financial (appearently this is the nr1 like we had industrious in civ3 and agri in c3c) It has mining providing the option to go for forest cuts (i think forest cuts are an extremely powerfull opening strategy and expect it to be patched later) It has agriculture, enabling you to work some of the more common bonus tiles and providing acces to animal husbandry, enabling you to work other very good and common bonus tiles. A perfect combination.
Industrious i think by itself is not an extremely powerfull trait, but it is at least a fair trait and it fills that culture gap by providing a cheap stonehenge.
Finally, i want to say, i also have only about 10 hours of play time now in civ4. So don't take what i say for wisdom yet
(but try using good argumentation if you think i am wrong
)
You probably have already noticed that i am a gamer who likes to analyse things a bit
The most important reason that i want to give civ4 a good chance is that they also tried to ruin civ3. When i first met the corruption in civ3 and the culture flips i also thought "do these guys at firaxis actually not like strategy games? Do they prefer sim city ?"
Yet, civ3 still ended up a good game and a true strategy game.
