This revision of World Cup Soccer ~ World Championship Soccer (Revision B) suggests bug fixes or minor gameplay adjustments implemented after the initial release on the Sega Genesis. The 'Rev B' designation indicates a later version, possibly addressing issues found in the first iteration.  Sega, the likely developer, is likely to have made these improvements. The core gameplay probably remains largely the same, but the experience could be slightly refined, with improved stability and potentially minor changes in balance or presentation.
