pros of colliseum - covers almost entire map, spits out 8 hoplites. very powerful if your fighting against one and your classical age. not sure how it stacks once im in medieval or gunpowder age. in end game (space age, future age expansions) those hoplites are going to be a very minor distraction. on flip side in end game the colliseums gladiator power you get once a day can be very powerful and could be a game changer in alliance wars or special events. think tanks with a power boost that only colliseum gives. forbidden palace gives you boost to medal farming. it does nothing for offense. it only helps on defense in how long it takes to destroy it. being a wonder it will have 4k hp like a towncenter...:
r 2k hp like the other wonders? in either case end game 2-4k hp isnt much. just like colliseum hoplites wont amount to much. but if you incorporate it into your defenses well enough it can prevent opponents from rushing what would normally be one towncenter with a rally attack. they can rally on one town center then have to rally on other town center. i dont know how hard that will be in enlightenment or space age. probably harder than dealing with 8 hoplites every 30seconds using tanks. im just not sure how much harder. put them on opposite sides of the map i guess could be annoying........tLdr........personally i favor the colliseum. because its boost to offense scales to end game. its very powerful mid game. and looks better than forbidden palace brown building.
