Grivier

my very very favorite is www.torncity.com.
its very attractive, with lots of features (more than i have seen in any other game) and together easy to use. anyway, be careful if you decide to try, its very addictive

i made a text based game .

gotta recode it though coz the way i coded it seems to lag the server.

http://www.travian.com

is also a well known browser based game.
I think its very good.
