Games have come a long way since Space Invaders and Pac Man. They routinely do have hundreds, or thousands, of interactive things. Especially things like RTS games. But also, even if you look at turn-based strategy games, which have a much more application-like interface. Every hexagon, terrain feature, and unit is interactive, along with a full application-like menu, statusbar, and UI system.
