Chicken-egg problem. You can't figure out what different people would like if you keep churning out the same things that once attracted a particular audience over and over again, just bigger and with more pixels. Change is the only way to attract newer audiences (see the mobile space for example.)

It's only a "problem" for large game companies with unimaginative executives. For indie developers it's a blessing, and rightly so.
