It's not as directly relevant to the original topic, but No Code's previous story game Stories Untold also has a great retro-computing aesthetic (and text gaming episode complete with clacky mechanical keyboard).
They're spooky point-and-click type games but both can be picked up for under 10 dollars together, for anyone into that sort of thing." />" />
Mind you, much like Mortal Kombat, not 'true' motion capture as we know it today with tracking software, but frame-by-frame animating actions performed by an actor doing the same actions.
Think I'm going to have to pick this one up!
It's neat so far, though it probably doesn't go far enough towards issuing commands to do things, there's a bit too much manual controlling since not everything can be done through commands (especially annoying with a keyboard that doesn't have arrow keys). The aesthetic is pretty okay, bit of retro and bit of Web 2.0.
