If you haven't heard, the Xbox 360 version of Castlevania: Lords of Shadow will ship on two discs (Limited Edition pictured above). Here's a tip: You can save yourself some precious disc-swapping time if you install at least Disc One to your hard drive.
Although Lords of Shadow's story is told in an episodic, linear fashion, you'll want to revisit earlier levels to find missing collectibles and beat any additional challenges. Without installing, you'll have to swap discs every time you want to revisit earlier levels. However, if you've installed the data, you won't ever have to swap discs again; you'll be able to continue playing with just Disc Two in the drive. It's an interesting way of overcoming the DVD format's size limitation -- a clever trick that could be employed by future multi-disc releases.
