Parents should also be aware that Quake III: Arena is brutally violent with tons of gratuitous blood spatter under war-like conditions. Satanic imagery like Pentagrams also adorn many of the Hellish looking scenery. Beyond the shocking content though, some kids may truly benefit from the sports-like competitive atmosphere and sense of reward that Quake III: Arena promotes.
We tested this game on an average consumer system that had a K6-2 400mhz CPU with 100-plus Megs of RAM and a 56K modem. We found that this modest setup was more than adequate for playing Quake III: Arena at its normal settings, but to play it at the highest levels of details, a truly top of the line system would be required to get smooth and adequate performance. Because despite being a well optimized game, all the technological feats that Quake III: Arena can accomplish requires some serious hardware kick. Those without a top of-the-line 3D accelerator need not apply.
Fans of FPSs looking for a more traditional single-player experience should stay away from Quake III: Arena since it was designed for online multiplayer gaming. Go with System Shock 2 or Half-Life: Opposing Force instead.
The more casual gamer and newbie looking for some online multiplayer action may be turned off by the intense and often unforgiving level of competition in Quake III: Arena. They may want to go with Unreal Tournament instead since it offers more diversity in weapons, options, and modes of play.
The hardcore Deathmatch purists looking for serious and intense competition and perhaps aspiring to be a professional gamer one day will be most pleased with the more refined and streamlined gameplay that Quake III: Arena offers. Though be warned that connection speeds onto the Internet still play a huge part in overall performance and competition.
