As for the bugginess, all games are released in batches, and each batch has bug fixes. This is for the most part transparent to the consumer, but the first version always has more bugs. The most famous examples are Zelda:OoT, which has different music in the Temple and fixes for some bugs with Link's sword, and Perfect Dark, in which a couple of the multiplayer levels are impossible to complete with three players, making it impossible to get all four stars in a couple levels.
