Summer Games (Europe) (Beta) indicates a pre-release version of the Summer Games title. This version would have been in testing before the final official European release.  The gameplay could be very similar to the final version but may contain bugs, incomplete features, or alternate design choices.  This beta version offers a glimpse into the development process and would be particularly interesting to those studying retro game development.
