Tbh it’s a not fair to put wonder in building list and compare them with aoe3 where aoe3 have different politicians instead of different wonders and it work mostly in the same way.
As a top aoe3 play and i played quite a lot the aoe4 beta, the asymetri in both game are pretty equivalent (bewteen aoe4 and aoe3 vanilla). The big difference is, in aoe3 vanilla all civ come from the same area, so it was easy to had very different mecanic later, in aoe4 we should have more asymetry in civ than aoe3 just because the roster are suppose to be more asmyetric (and that’s not the case).
I think aom2 is a better material for a few but very asymetric game
