Same as with "South America Trek", this game is supposedly educational but the misspellings (and the poor quality) negate such noble intentions. It may well be that the game was first published in 1986 instead of 1989, given that it is mentioned in other games in the series that year, but it can be the case that only copies of the later version 2.0 have survived. Supposedly there was a third educational adventure in the series, "African Safari", but it's not mentioned in later games and no copies seem to exist at this time, so maybe it never was released.
