In other words, to build a cannon requires saltpeter, iron, and a barracks.
I am considered weak to 'almost' everyone. Many times civ's will just declare war and attack each other. I still get occasional 'give me this or war', but it seems everyone is overly peace-loving (perhaps they are all smoking the special cigarettes?)
EDIT: Seems they are all getting back to normal, must have been nothing.
Still like to see the limit on buildings removed ... would be so nice.
Some have gotten the patch to work to where the human player does not have the option to raze either. I believe El Justo has this working in Age of Imperialism (IIRC); not sure what he did though; and it was with the no-raze only patch. Perhaps he can say he there was a specific no-raze which did this, or it was something else he did, which could be used similarly with this patch.
Others have said it worked for them though. I think Ares was one of them. I'm tempted to test it out again.
