Since SFML is a multi media library and not a game engine it is possible to create almost any type of game with it since the library is not dictating game genres etc.
However, SFML will only give you the basic bits that lets you draw stuff to the screen, play sounds etc. It won't do resource management, GUI, collision detection or other things that you may expect from a game engine - you'll have to build that stuff on your own (or use existing add-on libraries that others have already build, like "Thor", "SFNUL", "TGUI" etc.).
