Game of Thrones on HBO is a complete work of fiction so they aren't locked into any specific characters or events like "Camelot" (which may or may not have anything to do with reality). Instead "Game Of Thrones" invents its own kingdoms and characters leaving the writers a bit more leeway. The series is based on a series called "A Song Of Ice and Fire" by George R.R. Martin. The plot can be boiled down like this: Seven families fight for land and the throne, meanwhile a group of knights try to hold back evil at some remote outpost. Check out the preview below.
