While some of the basic rules of football are implemented in Champions of Europe, the game is notoriously broken, and does not make a distinction between the two opposing goals. This means players can score own goals in order to increase their score.
Furthermore ending the game at half time with a 0-0 draw is registered as a win, and finishing with a 0-0 draw automatically qualifies you for the final.
Champions of Europe was not localised for each country it was sold in, but rather than opt for one language (typically English), the teams use their native tongue to describe themselves (for example, Germany is known as "Deutschland" and Italy as "Italia"). Teams are selected by choosing a country on a wildly unproportional map, in which Iceland is exactly the same shape and size as the Faroe Islands.
Tying the game to UEFA Euro 1992 leads to factual errors, likely unforeseen by the developers at the time. Civil war prevented Yugoslavia from taking part in this tournament (being replaced by Denmark, who would go on to win, though both are included here), and "Russia" as this game calls it, would actually play as the CIS national football team, having qualified as the Soviet Union only to see the state dissolved in late 1991. The teams represented are those which participated in the qualifying rounds of Euro 1992, though does not take into account the separate admissions of East and West Germany (unified before any games were played).
