In an article over at Curmudgeon Gamer they take a look at the current library of GBA games. They analyze things like sequels, licensed games and remakes to determine how many GBA games are actually original titles. The answer? 9.1%! Only 9 percent of games on the GBA are original and of that list I could only recognize Golden Sun and Advance Wars. Over 50% are licensed games as well, confirming my belief that the Mary Kate and Ashley games are multiplying on the shelf at Best Buy when I'm not looking.
