Neverwinter Nights
According to wikipedia:
"Neverwinter Nights (NWN), produced by BioWare and published by Infogrames (now Atari), is a third-person perspective computer role-playing game that is based on third edition Dungeons & Dragons and Forgotten Realms rules (with minor changes). It was originally to be published by Interplay Entertainment, but the publisher's financial difficulties forced the change. Infogrames released Neverwinter Nights for Windows on June 18, 2002. BioWare released the freely downloadable Neverwinter Nights Linux Client in June 2003. MacSoft released a Mac OS X port in August 2003."

The extra Premium campaigns and the expansion packs were nice, though, giving you more hours of gameplay without any drastic changes.
Some of the mods are much better than the original campaign.
Hope this trend continues into the future games.
Still, i thought it was cool that they ported it to linux.
The game also has an almost limitless number of player-created expansion adventures, some of which are actually superior to those included in the game. In a fairly unique and surprising move, BioWare has published some of the most popular community-created expansions in their later compilations of the game, and on their website. Cool!
