Snowball Sunday is a winter/Christmas-themed snowball fight game for the Commodore 64, written by Ashley Routledge and David Saunders. There isn’t much information available about it online, but from what I can tell it was given away free with various Commodore magazines in 1988. It was also freely available for download from Compunet (aka CNet) – an interactive service provider that was accessed via dial-up, that existed from 1984 to 1993.
Micro Machines 2: Turbo Tournament is the even better sequel to the excellent Micro Machines. It is a single or multiplayer overhead racing game where you race different types of toy vehicles on a variety of miniature courses.
