That is the most defeatist thing I have ever heard. Should they have kept making Pong machine-clones when the Atari turned up? How about keep on just making games for those game centric PC's when the NES was selling like hotcakes, and keep on making light gun arcade machines while the Playstation was in the ascendant?
They're going to get the rug pulled from under them if they can't adapt to the changing times.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
