Browser games with management?

If you like browser games with resource management elements, I can advise you to try slope 3 for a change. Although it's an arcade and not a strategy game, it's addictive from the first second. If you are looking for more strategies, check out sites like Plarium or Armor Games, where you can find quality strategies with an economic bias. There are games with city management, armies and resource management, all for free and without installation.
