"Secularism" is only stronger than "Free religion" if you don't have more than one religion in any of your cities. So most of the time, by the time it becomes available, it is actually weaker. Still, your opinion is noted. "Labor union" is mostly about penalties. Penalties you recieve if you switch to it, and penalties you recieve if you don't switch to it. It's all about balance. Vanilla civ doesn't represent the vast labor movement of XIX-early XX in any way (American developers=not acnowledge such "commie" stuff? ), so we had to simulate the proletarian unrest this way. We'll probably think of something better later on (after BtS?). We're working on a completely new tech tree now. So it should be even better. Writing shouldn't come before alphabet, because early writing wasn't alphabetic in nature. Take cunieform, or hieroglyphics, or knots on a string - all these early form of writing come before development of a true alphabet, i.e. a set of symbols representing phonetic signs. Thanks for pointing out the bugs.
