Ben There, Dan That! is a humorous AGS adventure where Dan Marshall and Ben Ward star as themselves. Their initial quest is to fix the television signal so they don't miss an episode of Magnum, P.I., but instead they are soon transported through an alien environment. There they need to access different rooms to find a way back home.

The game uses a classic point-and-click interface with an inventory near the top of the screen and different actions available through cycling with the right mouse button. Players control Ben, but Dan is also available as a possible action, usually when Ben does not want to do the dirty work. The game contains many references to other titles and adventure gaming history in general.
