If you really like Risk but want something more, try this. It plays a lot like Risk in that you're doing area control and attempting to conquer lands controlled by other players. Add to that basic game play the fantasy theme and special abilities of the different races and you've got a nice gateway game for people who like Risk.
There is a lot of "take that" as you'll be constantly attacking each other so if you don't like that type of game then you should stay away.
