System Shock 2. The grandfather and holy grail of FPS-RPGs. It was so monumental back in 1999 that it shaped many elements of game design that have become standard practice over the last 16 years. Games like Deus Ex, Aliens vs Predator, Vampire Bloodlines, Doom 3, BioShock, Dead Space, and Fallout 3/NV, all owe their existence at least partly to the innovations established with System Shock 2. Even games like STALKER, Borderlands, and Portal have drawn influences from the almighty System Shock 2.
Despite its immense critical acclaim, winning numerous "Game of the Year" awards and frequently finding its way into modern "Best Games of All Time" lists, System Shock 2 wasn't much of a commercial success at the time. Falling between the cracks of Half-Life in 1998 and Deus Ex in 2000, its legacy was that of an obscure cult phenomenon that few people actually played -- but those who did loved it vehemently -- until BioShock came out in 2007 and renewed everyone's interest in its spiritual predecessor. Even then, finding a working copy was a little difficult, so the game remained largely unplayed and inaccessible until GOG and Steam released digital copies in 2013. Now you have no excuse not to play one of the greatest video games ever made.
The real question, however, as it always is with these "old" games, is whether or not System Shock 2 is actually worth playing in this day and age. After all, lots of old games just haven't aged very well, and why would it even be necessary to play System Shock 2 when there's already BioShock, a more-modern adaptation of virtually the same game design? The answer is simple: because System Shock 2 is a better game, and it still plays remarkably well, even after 16 years of aging. I'll get into more direct comparisons in another article; for now, I just want to talk about System Shock 2 as an independent game and how it's stood the test of time.
