... in IMM+ you might be easily beaten to wonders by the AI, multiple times
Deity Japan OCC Quick speed
Some tips I found useful:
- don't aim for SH/GL (focus on National Wonders early on instead), let AI spend the time to build it, it'll free up latter wonders for you (I got a lucky start with the Japan game).
- check trading screen early to see if Open border is highlighted to see which AI has early writing...same thing for Phil/RA; with good scouting of their land, you can guesstimate if AI is teching top or bottom line.
- beeline techs deeper in the tech tree that opens wonders, so you have 1st crack at it (ie. Pyramid/Hanging Garden; greatwall if bad neighbours).
- side track to MC for workshop, put in eng specialist if you got beat to all the early GE wonders.
- beeline Edu early if you can handle diplomacy, start PTower before University.
- beeline Ironworks, combo 1st GE for Taj (works better than rushing PTower in my experience, just build PTower straight as soon as Edu unlocked)
- use 1st GE for Taj/HCastle, depend on civ's UU thus path beelined; Askia/Mongo for example, the +2 eng gpp from HCastle will speed up 2nd GE in time for Taj.
- build other wonder in Golden age, rush buy buildings if really needs.
- this game, for example, I built wonders all game long...rush buy units/buildings.
- on huge maps with all the AIs...then don't bother with any pre-medieval wonders
