Like a Final Fantasy and Suikoden-based turn-based fight system? Chances are you will love Atlantica Online. This one MMORPG puts on a sandbox system that keeps all the cities in the world relevant when you've reached the highest level, unlike any other MMORPG that tends to let small towns dump abandoned.
Atlantica Online does this by allowing in-game guilds to own the city. These cities can be developed by adding various facilities that each has its own function. Not only that, in Atlantica Online all the "auction houses" in each area are different, so you can just get the goods at a cheaper price if you are diligent exploration.
The Atlantica Online battle system also allows for the emergence of mercenary systems, ie soldiers who will help you fight. Each mercenary has different abilities and can "evolve". For example Spearman can evolve several times and end up in Zhao Yun's class hero.
The Mercenary you recruit will not be with you forever. After some time passed, mercenary will retire and you have to recruit new mercenary and train it again. This keeps you active, and when you reach the highest level you will go back to the old area to find mercenaries and train them.
