Wish I still had interest in arcade sports games. Baseball Stars was absolutely fantastic. Hook up a second controller, two player mode, use one team and bean the other team, score 10 runs, game called, load up on cash and build up your team.
The only major issue was trying to successfully turn off the game. Hold the reset button down, press the power button, and release both at the same time. Otherwise, all your data gets completely wiped out.
