Wolfire, the charitable types developing kooky PC action game Overgrowth, don't just make games. They imagine what it would be like if people went and remade someone else's old games, making them as awesome in 2010 as they were originally.
Wolfire's team has posted examples of five classic games that "could still be milked, along with concept art for what the remakes could look like".
I'm not really sold on Shadow of the Beast, but the others? Perfect.
Shadow of the Beast
And now to finish, some rabbit-punching from Overgrowth.
