You're better off blaming the industry as a whole rather than Microsoft orAbsolutely. Although it's a bit different with Halo because in the cases of Halo: CE, 2, and 3, they didn't lock any of these in-game items behind preorders or SKUs. You can make any color Spartan. You can build any emblem. You can wear any armor (that you unlock). So what we have seen is a shift and a HEAVY escalation.
2001 Halo: CE - 0 disc-locked items
2004 Halo 2 - 0 disc-locked items
2007 Halo 3 - 0 disc-locked items
2009 Halo Wars - 2 disc-locked items
2009 Halo 3: ODST - 1 disc-locked item
2010 Halo: Reach - 4 disc-locked items (I had forgotten about the Gamestop chest piece)
2012 Halo 4 - 67 disc-locked items
It's worth complaining about. It deserves contempt, especially when it goes against the legacy and spirit of the franchise.
