The best mmo browser game I've played to date, immersive gameplay and has a great social aspect.
Game mechanics are very balanced, and is not as "pay-to-win" as most other "free-to-play" titles out there. I've personally enjoyed the social aspect of the game as it makes the game much, much, more fun and that is what keeps me playing in the end.
The devs have also been introducing new content every now and then, and more exciting things are in the works, so there is much more to look forward to.
There are different ways to play this game as well, whether it be as a peaceful merchant building resource cities and trading resource, or as a warmonger who builds military castles and cities. It all depends on the pace you one to play at, every person will have his/her style.
Although gameplay is slow in the first few months, it picks up immensely as alliances battle it out for control of continents. Millions of troops go out to war every single day, castles are crushed, captured, or defended succesfully.
The goal is to have 8 palaces of each virtue, and whichever alliance accomplishes that wins the crown. Therefore it is important to have a close group of players working together.
All in all the best mmo browser game I've played to date. Would recommend it to any and all.
