video game lag
When good video games are released too quickly and you don't have time to finish the video game you're currently playing before you get the new one.
I was playing Baten Kaitos but then MGS3, Kingdom Hearts: Chains of Memories came out and before I could finish those two, Growlanser Generations was released.  Before I could get through Growlanser, the Wind Waker was re-released as a greatist hit.
