Well, Atari burned their bridges with
Enter the Matrix. That sold a vast number of copies but was generally considered to be a poor game; to expect people to shell out for a
second game that had received mediocre reviews was perhaps asking a bit much.
As for Shiny, I've always found them a bit mediocre (sorry!). They're a bit like Peter Molyneux in failing to deliver what they promise, but they make it worse by never actually aiming that high
