The funniest thing about the Da Vinci Code is that it offers nothing new. The ideas it extrapolates are genuinely old hat. Still, it’s a huge commercial success. Clearly someone just had to write these things down in a format (in this case, modern pulp fiction) that is accessible to a large public audience.
But yeah, I’d love to see another GK. Perhaps another developer (Revolution?) could acquire the rights and hire Jane Jensen to write the game for them . . . ?
