Besides Heroes 3, I haven't found any other game that I enjoy playing for a long time. Other games get boring after a while. But, for example, I think the old games are the best! For instance, Quake 1, Doom 1, Hexen, Age of Empires 1, Majesty, and Diablo 1. Maybe the graphics are blocky, but there's such a great atmosphere and interest; you can feel that the developers put their heart and soul into the games. Medal of Honor and Disciples are also pretty good.
