- TRIVIA -
Egg Venture was a joint project between arcade parts company 'The Game Room' and 'ICE' (Innovative Creations in Entertainment), each of whom released their own version. The game was programmed by Kyle Hodgetts and does have several minor glitches, mainly down to the nature of the hardware. Problems with the availability of components meant that Kyle was forced to duplicate the sound system three times on the board to achieve polyphony, rather than using a simpler, but more expensive YM/OKI combination.
Egg Venture does not have an ending and it's only scoring system is the printing of the Dynamic Play Adjustment skill ranking after every 'day'.
The game appears to use (in places) the bass line from 'The Great Egg Race' by Martin Cooke and Richard Denton of BBC Records, although this is apparently a legitimate use, as the music came from a royalty-free library disc.
Following the success of Egg Venture, or more likely to fix the bugs present, a 'Deluxe version' was made.
The Egg Venture characters were later used in a kids redemption game.
