And here we have a tape copyrighted to 1981, the last year the Mego 2-XL was marketed. This one also has that back label advertising other games.
Since there isn't much to say about the cartridge content, let me talk about that back label. It is the same back label that appeared on one of my "Animal World" cartridges, which is copyrighted 1978. Both have the same game list, and the list includes games from 1981, such as "Amazing Sports Feats". This leads me to believe that the list was added to cartridges that were manufactured in 1981, regardless of the content copyright, as a way to advertise more tapes. Perhaps they thought it would help shift more stock.
