Neverwinter Nights has 3 Campaigns (one is the story of Neverwinter's Tragedy, where a plague manipulated by sorcery and an ancient evil race stains the honor of the Jewel of the North, another involves retrieving artifacts stolen from your teacher, a Harper in hiding...which leads to the third one which was the Cania one), 4-5 "short stories" that added content and were open-ended (1 is a pirate game - must play, another involves the Shadowguard, another is the first of an incomplete "Witch stole your soul" series, and another has you take over a kingdom, as you are the child of a demon, favored by Mistress Death, and fighting your demonic illithid half-brother...while accompanied by a cowardly wererat, a scarred nymph, an exiled Aesir, and a libertarian Rakasha.), and...literally thousands upon thousands of mods...

Neverwinter Nights was a game whose stories were somewhat copied from Baldur's Gate, whose graphics are really dated, and whose gameplay is oldschool...but the stories, the characters, and most importantly, the fan material kept the game alive for almost a decade, spawned a similar (if better graphics/more buggy) sequel, and now has inspired an MMORPG with some modding ability. I want to really get to trying that one out, but it is not my first priority ;_;...

Neverwinter is THE create-your-own-world/story/universe game of the 2000's (not necessarily the 2010's)
