I recently began playing Age of Fable and it is alot of fun. I think anyone who enjoy fantasy rpg's will like it. Especially if you want to play something like D&D but don't have any players or Dm's around or only have a short amount of time.
Its free browser based and you can save you game. Its made by James Hutchings of teleleli.blogspot.com/
You really need to check it out even if just for five mins to see what its like. I don't know if everyone will like it since its mostly just reading and choose actions but if your into table top rpgs and reading or writing blogs then I'm sure you'll enjoy this reading. It also has some great artwork to go along with it.
Soon I am going to be reading and reviewing James' book "The New death and Others" But if Age of Fable is any indication I think I am going to definitely enjoy his books.
