I understand everyone wants to make a cool browser MMO type game, but it gets a little out of hand. I have seen countless games like this that are all the same thing, build buildings, wait an hour, and do it again. Also, they don't seem very polished, and is very hard to play, because it requires so much time to manage and build everything. If you want to make an MMO browser game, make sure that you have features that are unique to your game, and blow the others out of the water. Also make sure the game is accessible and fun to everyone, not just people who play the game all of the time and have massive armies.
