I'll preface this by remarking I haven't played Civ V for several months now.. So I'll probably not remember enough to answer all your questions accurately ..
"I have been trying this for a few days now always Oxfording Industry first. You suggest going to Artillery first? "
Think artillery first is better most of the time (especially if rough terrain // not a lot of highly promoted xbows//AIs got to cavalry already)
"What are the usual turn times for these two in most of your games? What is the usual Science Cut Off point?"
Don't remember sorry ..
"Is it after Edu and getting up Unis? Should you have 3 Unis or just one in the Capital?"
Will definitely need some universities ..(the more the better, even go astronomy for observatory if high pop city near mountain)
"Do you try to pop any GS's or do you just pop all GMs?"
Will need to pop GS to get artillery faster time..
"Are you always able to get to Ideology first when teching Artillery before Industry?"
Nope.. Sometimes deity AIs get ideology first.. Worst case scenario - multiple AIs get autocracy and I lose free social policies.
"What is your target Population for your Capital and Expos before you stop growth?"
I don't really do that.. When I got the endgame tech and disable science - start pushing gold/production - then I stop growth ..
"Do you find yourself making detours to BW or Sailing before you research Education?"
Yes.
"What is the tech path after Education. Do you Beeline Machinery? Beeline Artillery after that and go up to Industry? What is the next tech path after that... Rifles I presume? Im guessing after that it should not matter since the game should be about wrapped up?"
Sometimes I go machinery before education and try to steal education with first spy..If I try to mix in other unit types (minutemen // ..etc) education first ..
Chemistry, Military science, Artillery, Industrialization, Biology, landship tech, combined arms(tank tech)
"I find it easy enough to save up gold but sometimes I feel like I am wasting some of it buying Hexes in my cities. What are the do's and do not's of using your gold before it starts to roll in after Commerce?"
I buy a lot of city HEXes myself ..University/Observatory in capital(high pop cities) are good ways to spend gold .. Cultural city state allies are also worth the gold..Strong army neighboring CS is also high priority (they could do massive damage if you enemies get them)
"Do you ever get into building Barracks and other buildings into Military Academy?"
Core aspect of this strategy (allows you to ignore AI ideology and pick autocracy) ..
"I also find that if you can get up a Religion and use Holy Warriors it is a very big help at the start? What are your thoughts on this?"
Never tried it .. The shrine costs hammers and is seldom a guarantee for a religion so I usually skip it ..
"What is your usual Autocracy Path/Choices or is it always the same?"
Not the same.. Depends how much culture // many free autocracy policies you get.. Sometimes you must make due with mobilization alone.. Some perks are situational (might need the doubling of strategical resources on some maps (oil))
"Do you try to win WF or just get the 350pts for a free Policy or do you not even worry about the WF?"
Always propose it ASAP for diplo boost.. Always 350 hammers only for free social policy ..
