Sega developed an arcade board based on the Saturn's hardware, the Sega ST-V (or Titan), intended as an affordable alternative to Sega's Model 2 arcade board and as a testing ground for upcoming Saturn software. The Titan was criticized for its comparatively weak performance by Sega AM2's Yu Suzuki and was overproduced by Sega's arcade division. Because Sega already had the "Die Hard" license, members of Sega AM1 working at the Sega Technical Institute developed "Die Hard Arcade" for the Titan to clear excess inventory. "Die Hard" became the most successful Sega arcade game produced in the United States at that point. Other games released for the Titan include "" and "Virtua Fighter Kids".
