ok, heres my critique of tier 3:
Theology: looks great
Arcane Schooling: looks ok, i wouldnt mind a different name though

maybe Colour Focus?
Revelry: Name is too similar to festivals. consider a different name perhaps?
City Planning: nice tech, but a more appropriate name would be 'irrigation'. but its prereqs do not really logically flow to irrigation.
Riding: good

i also like charioteering and logistics changes.
City Defence: Nice tech
Engineering: Good
Renaissance: name isnt really appropriate to a single tech esp for a fantasy setting. id much prefer a different name.
Entertainment: again, too similar to festivals and revelry. something like 'environmental manipulation' (as in enchanting stuff (enchanter), magnifying acoustics and making insides of buildigns seem bigger (theatres and opera house)
Archeology: im unsure why the Archives are not enabled by THIS tech, and also why it require city planning. itd be better to require Renaissance and move it to the next era methinks.
Mounted Warfare: looks fine
War Machines: looks fine
Aesthetics: fine
Divine Service: Fine
Decadence: Fine, but if it requires Renaissance itll tangle teh tech tree up
Tactics: fine
Machinery: fine
Seafaring: Fine
Religious Law: fine
Arcane Warfare fine
Invasion: Not best name, surely there would have been invasions prior to this tech?
Vasselage: nice tech but io dislike the name and position in the tech tree. id ratehr call it slavery and have it require conquest. (ill show you waht i mean later with a pic)
i just tried to design the tech tree again but it crashed again and im too tired to bother redoing it now
