Grand Slam - The Tennis Tournament is the European release of a Sega Genesis tennis game. This version likely shared core gameplay with its Japanese counterpart but potentially featured language changes, altered rosters, or other regional modifications to suit the European market.  The development and publishing details remain largely undocumented, though Sega's internal or licensed developers remain likely candidates.  Gameplay would likely have centered around classic tennis actions and strategies.
