System Shock's one of those games that lots of descendant creations owe a huge debt to. If you're a fan of moody, story-centric first-person experiences like Deus Ex or BioShock, then you should be watching some of System Shock's creators play it right now.
Programmer/designer Marc Leblanc has been livestreaming the first System Shock for a few hours now and has been joined by other former Looking Glass Studios peers like writer/game-maker Austin Grossman. They've already talked about how Zelda and various Interplay titles influenced the creation of System Shock. Also, Leblanc said that he approached EA to see about potentially crowdfunding a System Shock 3. Turns out nobody knows quite who has the various rights to the various pieces of the System Shock property. They're answering questions from chat so, if you have a burning question about an all-time classic PC game, then head over there.
