In my opinion, the current best web based on strategy game would be Utopia. This is one of the best game to play if you like to manage your own province with aspects like growth, economy, military and so on. You decide what are the percentage of banks or barracks in your province. The army draft rate is also decided by you to blend the game into your leadership style altogether.
The game is based in medieval time, the age of might and magic. The land of knights, lords, barons, viscounts or kings. Your province will be placed within a kingdom which consist of more provinces. The best part is all the other provinces are managed by players all around the world. You will be subjected to the rules of the kingdom set by its monarch. The very monarch begins just like you, a province will only be throned if the majority voted for him or she.
There is no graphics in this game as it is purely based on strategy, logic and calculation. There are also many other aids that can provide you with more comprehensive formatted calculations for your perusal before making your decision whether to attack or not.
This game has been around for many years and it is still going strong. The game will reset itself every few months for a fresh start each time for every provinces during new ages. This game do not requires you to download a client, which means you can play this game anyway by just using your average browsers. Plenty of fun and I recommend that those who likes strategy must give this web based online game – Utopia a try.
