The Colossus is MUCH stronger than the GLH on island maps, since the GLH will be close to obsolete when you discover other civs and the trade routes become intercontinental. Delaying corporations doesn't make much sense, because it gives an extra trade route in itself and you'll want the mining corp which is not far away. It's still a good wonder of course, giving each city two free commerce initially. But the colossus will give each city three or four times as much, and some cities even more. Anyway, to my point of the Inca being one of the most powerful island map civs, they can usually get both!
Pretty much agree there, add the Moai Statues to your specialist city and you got a definite powerhouse.
