Ed Fries got a taste of game development in his teenage years, developing
Atari 800 games at home. Fries took a summer internship with
Microsoft in college and eventually joined the company. Fries left Microsoft in January 2004, after 18 years with the company. the Atari 2600 retained a dedicated hobbyist industry who still bought and played classic games. and found the challenge in developing
Halo 2600 one of adapting to constraints. The Atari 2600 has much less space and memory than was available for
Halo. With only 128
bytes of RAM, drawing Master Chief was difficult, and creating a game with other characters even more so. Fries later stated that making the game taught him that constraint is sometimes a fuel for creativity, comparing the process of adapting
Halo to the effort in turning a novel into a poem or haiku. "It felt more like writing poetry than it did like writing regular code", he said. "It felt like everything had to be so tight, so perfect. If even one of these tricks didn't exist, if I didn't have this incredibly clever way of drawing this sprite, or if I didn't have this incredibly sick code for drawing the missiles, I wouldn't have been able to fit it in. I couldn't have made the machine do what I wanted it to do." Fries pointed to other artists' work such as
Bach's fugues or elaborate
origami as examples of deliberately setting constraints to create something more interesting. The full game takes up just 4
kilobytes of space. ==Reception and legacy==
