Historically, the number of launch games has been important. The more games there are available at launch, the higher the chances that players will find something that interests them. However, the same importance applies to game quality: quite simply, poor quality games don't sell as well as high quality ones.
When gearing up for a major console launch, developers and publishers have a decision to make. They can release a large number of launch games, often accompanied by the promise of more soon after launch, or they can come out with a few extremely strong titles, or a killer game. While coming out with a large number of extremely strong titles is of course preferred, this may not be practical. To balance these choices, developers will very often supplement one or two strong titles with third-party or licensed titles to bolster the number of launch games.
