* AcceptableTargets: Elvis impersonators. Whenever they appear, killing all of them will give you a bonus, as well as the announcer [[LargeHam bellowing]] "'''[[IncrediblyLamePun Elvis has left the building!]]'''"
** AcceptableReligiousTargets: Hare Krishnas show up in the third district. As one of the factions you can work for. About as serious as their depiction of the insane, TheMafia, TheMafiya, the {{Yakuza}}...
* AntiClimaxBoss: All of the bosses, once the player has completed all of the missions. They come without reinforcements despite not being especially strong in any way - thus, the final mission of each level is just to kill three random enemies as they come.
* EarWorm:

* ThatOneSidequest: Kill Frenzies, the equivalent of rampages in later games, in the PC version. They aren't particularly hard in the first district, but become one of the hardest challenges in the whole GTA franchise once you reach the second district. They start requiring killing cops or destroying cop cars instead of civilians or regular vehicles, which not only is more dangerous, but also more annoying since usually there aren't enough cops chasing you (and therefore you'll run out of time). Besides, there's a notable GameBreakingBug which corrupts your savegame after completing a Kill Frenzy activated by entering a vehicle initially place on a trailer. The only known player [[https://www.youtube.com/watch?v=U9uSWI4chx0 who has proved to have completed all them]] did so through different exploit and glitches.
* WhatAnIdiot: Incredible stupidity among non-playable characters is incredibly rampant, whether by design or by programming limitations or [[ThrowItIn both]]. Even aside from flat-out cases of TooDumbToLive, there are forms of stupidity not directly lethal to oneself, such as a cop not considering it suspicious that you would be punching random civilians in front of him.
