Have a N.I.C.E. day (1997), an arcade racer focusing on stunts such as long jumps and loopingswas Synetic's first release. The game was unusual for a racing game in that it offered only three basic car models that could be tuned and modified by the player to suit a wide variety of different driving styles. According to statements made by Synetic employees on their website's forum, the term "N.I.C.E.", which also appeared in Synetic's follow-up title, was initially an abbreviation for some concept in the game, but apparently none of the team members remembers what it stood for.
