technology". The Nintendo-Pak and Punch-Out hardware also have a limited game library, whereas the VS. System accessed a wider variety of games, by easily converting Famicom games. Nintendo of America hired Jeff Walker from Bally to help market the VS. System in North America, where it debuted at the 1984 ASI show along with Punch-Out in February 1984. Reception Upon release, the VS. System generated excitement in the arcade industry, receiving praise for its easy conversions, affordability, flexibility, and multiplayer capabilities. Eddie Adlum of RePlay magazine said Nintendo had suddenly become "the big guy on the block" in 1984 due to the VS. System, which "not only meant interchangeable games but interaction between players on dual-monitor games". However, the graphics received a mixed response. Roger C. Sharpe of Play Meter magazine called it a "highly attractive and open-ended interchangeable game system featuring excellent graphics and realistic on-screen visuals" in 1984. However, the VS. System received some criticism for its graphics being technologically weaker than more recent rival arcade systems, and than Nintendo's own powerful Punch-Out arcade hardware. In Japan, VS. Tennis topped Japan's chart for table arcade cabinets in April 1984 and May 1984, and VS. Baseball topped the chart in June and July 1984. By 1985, however, the VS. System had declined in Japan, which led to Yamauchi deciding to withdraw Nintendo from the Japanese coin-op industry in late 1985 and Nintendo focusing more on the Famicom. In North America, by contrast, the VS. System became a major success. Following the arcade success of sports video games such as Konami's Track & Field (1983), Nintendo capitalized on this trend with several sports games (Punch-Out, Vs. Tennis and Vs. Baseball) that took the US arcade market by storm; Sharpe considered Nintendo "a force to reckon with" based on their strong performance. The VS. System was declared an "overwhelming hit" by Play Meter, attributing its success to "good games and low price". Between 10,000 and 20,000 arcade cabinets were sold in 1984, and individual Vs. games were top earners on arcade charts. VS. Tennis topped the arcade charts for software conversion kits in July 1984 (on the RePlay charts) and August 1984 (on the Play Meter charts), and VS. Baseball topped the charts from September through November 1984. Hogan's Alley and Duck Hunt then became even more popular in American arcades, popularizing light gun shooter video games.
