in case you haven't read the basic guide then let me copy it for you: ''hen one alliance completely builds up and controls 4 of the 7 World Wonders then they will have 'won' that world. The alliance that does so will recieve the Master of X award, and also be given a 10% increase in their favour cap on Hero Worlds. An alliance can then go on to complete the remaining Wonders to achieve the Ruler of X award.''
that means the goal to aim for is to complete 4 WWs before anyone else does. as for completing all 7 of them, you can do that anytime you like and you don't even have to be the first to do it, that is only for the prestige. besides, WWs don't even give some significant bonuses. it took me a while to sit back on my chair after falling from it from that laughter, after reading that the colossus grants you 10% faster victory procession. innogames, really? not to mention simmers who can't remember when did they run a victory procession for the last time
why am i talking about WWs so much all of a sudden? i don't care that much
