That oxford was 25 turns lol. So I started it in a crap city so that I could pop it whenever I want later on. I mean in the end it is worth basically free plastics or globalization or whatever, how bad can it be? Get plastics 8-9 turns sooner and rush buy a bunch of labs with faith? I dunno, didn't seem THAT terrible.
It's not about being good or bad in and of itself but WHEN and WHERE you build it.
Part of making the best decisions is choosing the build the right thing at the right time in the right place.
Questions that feed into that:
- is this building/wonder going to make an immediate impact?
- should I really have built it earlier?
- If I build it now, will I finish it in time for it to make the right impact?
- Is there a chance someone else might build it first (with world wonders?)
- Am I building it in the right city?
- Is this a good use of the hammers I have right now?
And so on...
So for example, rather than build Oxford in your worst city and have it take 25 turns, hwy not build 2 buildings in that time in that city, and then build Oxford in your capital 20 turns later, where it will take 5 turns, or whatever?
And even before Oxford, if you've gone Liberty, it's a good idea to go to Metal Casting before Education, so that those smaller cities can build Universities in less than 10 turns each once Workshops are up. Going Education first would mean having to build Universities in 15-25 turns and then Workshops. That's clearly the wrong way round.
If you want to improve your play, I recommend watching some videos, by say Acken, MadDjinn, Moriarte, etc. and watching how they do things.
