* EarWorm: [[https://www.youtube.com/watch?v=14eEphzk4Ec The main theme]], especially the FM Towns version.
* GermansLoveDavidHasselhoff: Was hugely popular in Germany, possibly even more so than it was in its own home country, with at least four fan sequels originating there.
* HilariousInHindsight: Cash Cards have become quite popular TwentyMinutesIntoTheFuture. Of course, we call them "Debit cards" these days. Sure, [[OlderThanTheyThink Debit cards have been around since the 1970s]], but they have become ''much'' more common.
* ScrappyMechanic: Having to go to the airport and back to travel around the world and the need for ''connecting flights'' gets rancid very quickly. Traveling also costs good money, which discourages free, happy go lucky exploration early on, and even if Zak can get more money later, the rest of the characters don't, directly. A torpid logistic nuance that kills gameplay while only adding constriction and apprehension. To make it worse, in most versions, copy protection checks had to be passed in every flight outside the US.
