Stonehenge and the just-departed Pyramids are getting heavily victimised - but I think at this stage it's probably not wholly unjustified. Stonehenge deserves to stay somewhat longer since it comes so early that that +5 faith equals a lot in the long run (yes, you can get a pantheon to do the same thing - but (a) Pantheon + Stonehenge = more faith, and (b) Stonehenge instead of a pantheon means culture farming or Messenger of the Gods are available to you, both of which will be superior bonuses if you're not going heavy religion). However, +1 won't save it at this point so I won't waste a vote on it.
As for the poor Pyramids, they probably did drop at about the right time, but now that Tradition is my go-to policy most of the time - and the only thing I much miss from it is, in fact, the free worker - the Pyramids are an indirect way to get that, and being able to grab strategic resources as they become available with a 25% improvement speed boost is more valuable in the long-term than people looking at Pyramids and thinking "Two free workers - want it early or never" gave it credit for.
Anyway, my votes:
Petra again, because it's the two hundredth anniversary of its rediscovery by Europeans this month.
Brandenburg Gate: I like this Wonder, but then most of the remaining ones are ones I either build or, if not, I should build more often (Big Ben, Chichen Itza). Brandenburg does come at a useful time, since it shortly predates the transition into air power you can't upgrade to from earlier units, but its value is entirely contingent on building the full suite of military upgrade buildings - it's not a Wonder with an important stand-alone effect. It's also relatively less useful for domination victories than other types, since by the time it appears the units you can upgrade will have seen so much combat they should have the full suite of good promotions - and while popping units with three and a half promotions looks impressive, for most other victory conditions you don't particularly need them.
Machu Pichu is just one of my favorite wonders, I will often go out of my way to found a city to build it, and will prep for war once I know which AI beats me to it if they do. When it can give +100 a turn it is just astounding. Always useful to have and it scales.
Nice to see this finally getting some love - it was oddly neglected for much of the early voting, but it's one I'd like to see make the final four (the Wonders I'd be torn between calling "the best", the others being The Oracle, The Hanging Gardens and Petra. All of the remainder are too limited or simply not as good, in my view, with the possible exception of Pisa).
STOP THE HUBBLE HATE GUYZ
Stop upvoting it then...
Seriously, at 28 at the moment I think it's probably about where it should be in relation to the remaining Wonders at this stage.
