Video games are my main hobby, so I don't really go through any phases where I don't feel like playing anything, but I do sometimes lack the motivation to play games I haven't started or finished yet, so I do go through that sort of slump every so often. But there's some games I'm pretty much always in the mood to play. Usually it's a puzzle game, like Tetris or Puyo Puyo, but sometimes it can be other genres; I never go too long without replaying a Xenoblade game for instance.
