And this, my friends, is why publishers like NIS and Atlus are doing terribly well despite not having many games that even get close to cracking the best-seller list. They develop and publish games smart; they keep the budget down, they concentrate their marketing on demographics they know will like the game, they make the game in batches and create more as the need arises. They sell games with the idea that while the first few weeks will be your biggest sales, you can always sell more later. They somehow sell based on the premise that if your game is good, people will hang onto it, and more will buy it new because used copies are hard to find.
And these are also the companies that thankfully will stick around should another video game crash happen. These are the publishers that already know how to turn a profit in a relatively saturated market, and they'll thrive even more if the heavy hitters sink with the industry. Dare I say they might even hoist the industry up on their backs and save it down the line, if that prediction happens.
