If Nintendo had launched a GameCube 2, it definitely would have had some incredible games. Nintendo always pumps out some top-rate games for its platforms and GameCube 2 wouldn't have been any different. As we alluded to earlier, however, third-party support on the system would have become a problem when compared to Xbox 360 and PS3, and after some time the Dreamcast comparisons probably would have kicked in. After all, Sega's much beloved system was perceived as having a high quality software library (fueled in large part by Sega's first-party efforts), but the console's lifespan was unfortunately cut short due to the market conditions and Sega's poor business position.
This brings us to our last point...
