When the very first Macintosh computer came out (128K RAM, 400k floppy) in 1984, my brother Randy Wilson wrote a video game called originally "Gravity Well" internally, and eventually "Continuum" when it was released (when released it was unable to run on the 128K Mac, instead it required the very next upgraded model of 512K).

Currently, the value of a Complete In Box (CIB) copy of Continuum is estimated around $99.00. For collectors looking for a Loose copy, transactions usually happen around $45.00. The price gap suggests that the box is relatively common.
Released in 1986 on Vectrex, this title is an interesting piece for any Vectrex collector. The game's value is rising, a sign of growing interest from collectors.
