Softdisk's primary business was publishing monthly disk products, but the quality of the software suffered due to the one month time limit. Romero's decision to release games at two-month intervals increased the game quality and allowed Carmack more time to plan and experiment with his game engines.
id Software immediately entered into a publishing contract with Softdisk to supply the abandoned Gamer's Edge department with games for the year of 1991.
After the group left, Mike Maynard and Jim Row took over the department and spent most of 1991 learning Carmack's engine and Romero's tools and producing games so that when id stopped supplying Gamer's Edge with games (at the end of 1991) they could continue releasing games they'd stored up.
Gamer's Edge lasted until late 1992 when Mike Maynard and Jim Row left to form JAM Productions (licensing the Wolf3D tech) and create the Blake Stone series.
