I'm an Odyssey collector myself, I own almost every game for the system including Percepts in the original shipping box and the 1973 set with the 2 1972 games wipeout and volleyball it came with also still in the shipping box.
The only game I am missing is Soccer from the Export version.
I also own the rare white carry case.
Which brings me to my question.
Since I have collected almost all the games I've started collecting different variants of the system.
If anyone has or knows someone who has the German ITT Odysee, the Mexican version called the Odisea or the Export version from 1974 with soccer, please let me know right away.
