 The original idea was to develop a "design, print, cut-out and assemble gymkhana".since both Peter and Keith had daughters it seemed a great idea, when they presented the idea to a commercial software company they were told that girls didn't use computers nearly as much as boys and, if they were to develop a similar product for boys, then the firm would be interested in discussing it further.So they set to work, and designed the first (never released) version of Designer Castles, when they presented this, the commercial company was highly critical.
