21 Days Later: Vectorized

The Theme

From Asteroids to Vectrex (GCE’s system), vector graphics have a special place in the history of gaming. First pioneered by Cinematronics in the 1977 game “Space Wars”, the method of drawing sharp geometric shapes with straight lines harks back to the days when “simplicity and intense gameplay” were the mantra of game players and developers. For the next 21 days, iDevGames invites Mac developers to go retro by developing a game that captures the glory and spirit of vector graphic gaming.

The theme of the first “21 Days Later Contest” is called “Vectorized” and it challenges developers to go retro by programming a game that captures the glory and spirit of vector-graphic style gaming. More information about the competition and how to enter can be found at the official “21 Days Later Contest” home page:
