TOP Web browser games in Europe(Status and some information)

Hi all,
I've just searched some information of web browser games in Europe. And I started playing "The Settlers Online" which was developed by Ubisoft on Sep 2010. I didn't know how it is famous so far. I think it is quite loose, but still enjoy. And there are lots of users i can see them on chatting system. It is pretty impressive.

Here you go. I've chose top of six games and their some simple information is following. And I would like to share some information, but I don't know some of data. I would be grateful, if you could you provide me that I missed.

Actually, we have tons of games and I have no idea which one I should play. In my case, when I have time, I login several web games, and play at same time. It is funnier than massive 3D MMORPG games. :')

It is sunny Friday here. Enjoy your Friday and week-end as well.

Cheers.
