FIFA International Soccer is a wildly unpolished soccer game. There's no real players, no create-a-player, only national teams, the ball flies around the field like crazy, there's basically no passing, and you can header a goalie throw in a way that allows you to kick it in the goal right after, bypassing the goalie (I call this technique Goal Theft), but it all comes together to make an incredibly fun game.
I'd love to see this near-fantasy version of FIFA become available for players again. This was also the first soccer game ever to be isometric.
