Well, honestly, you aren't missing all that much. The Odyssey 2 might have done well if they only had the Channel F and the RCA Studio II to compete with, but the Atari 2600's flexibility made the Odyssey 2 look pretty unsophisticated in comparison. There are a few really solid games on it (Turtles and Killer Bees spring to mind) but most of its library is merely okay. A good Odyssey 2 emulator will suffice.
