lotgd.net - I don't play any more but if you haven't it's great fun. Lots of 90s nostalgia from LORD/Usurper/Exitilus in dial up BBSes
There was a similar non-terminal MUD-like game called Phantasia as well. Heavy LOTR themes, Java client, permadeath, players could ascend to become Steward, King, or even Valar with special abilities that affected other players. It was available way back on Netscape and is still scraping by.
Dragon Court was another MUD-like. Java with painted art graphics in the browser.
