Enjoyable Browser MMO?

Hello, I'd like to know if any of you know any good browser based games out there that are Ether medieval themed or Scifi.That are not text basted and for graphics i don't really mind 2D or 3D would be cool.And gameplay kind of like runescape, well just the same basic idea of it =D.

Note, I can Download and can do P2P So do tell if you have any.

Sorry if its asking a ***** much.

EDIT:Sorry if this is the wrong fourm, but i saw other posts asking about games.
