$80,000. According to Rubin, Way of the Warrior marked Naughty Dog's exit from game making as a hobby and an entrance into game development as a profession. While they still lacked a business plan, Rubin insisted that designing instinctively was the "appropriate way to make games", while Gavin added that self-funding without the oversight of publishers pushed them to devote their time and resources more wisely. Around the start of Way of the Warrior'''s development, fighting games such as Mortal Kombat, Street Fighter and Samurai Shodown had become popular in arcades and on home consoles. Rubin observed that the direct nature and smaller size of fighting games in comparison to role-playing games made them easier and quicker to make. Gavin explained that "You make one background and one character, you play against yourself, and you’ve got a playable game. You could start working out balance issues and play issues and stuff." Gavin and Rubin aimed to create an over-the-top and "slightly more comedic" Mortal Kombat, primarily inspired by a number of Hong Kong kung fu films they had watched together. Knowing that they would have to work in the same location to make the game, Rubin attempted to convince Gavin to move to Newport Beach, California. However, Gavin was still attending the MIT, and so convinced Rubin to come to Boston, acquiring an apartment for them to live and work in. Although Gavin and Rubin intended to replicate Mortal Kombat's visuals with a digitized approach, their restricted budget disallowed a chroma key system or any kind of motion capture backdrop. Thus, they bought a cream-colored screen and nailed it to the living room wall, covering the apartment's only windows as well as the air conditioning vents. The position of the screen, improper lenses for their camera, and small size of the apartment complicated the filming process. To film the moves in the game, Rubin had to open the front door and shoot from the apartment hallway. This confused and disturbed their neighbors, who mistakenly believed that the pair were filming kinky pornographic films. Gavin and Rubin enlisted friends and family members to portray the game's characters; most of them worked for free, as Gavin and Rubin were unable to pay them. The game's costumes were thrown together and purchased from a single store in Boston's Chinatown, with Gavin and Rubin not knowing what a given character would look like until
