I'm a big fan of interactive fiction (think Zork) where there are no graphics, just talking to a parser. This is one neat area, where the old Infocom games are well respected (see "Get Lamp" documentary on YouTube) today, but it is well recognized that the technology and text game complexity has reached entirety new heights that have pushed the boundaries forward immensely.
