Actually, this happened to me too. I started Banjo-Kazooie in 1998 and finished it in 2008. I found every damn collectible except for one stupid musical note in Click Clock Wood. I didn't want to finish the game without it, so I put it aside...and there it waited for a decade. Then I bought Banjo-Tooie from a vendor at Comic-Con in 2008 and decided it was time to see the end of Kazooie.
