Allistair Pinsof for Destructoid:

Even companies with net worth in the millions are guilty of turning in a rushed assignment from time to time. While Microsoft Studios seemed pretty confident getting behind a Xbox Live Arcade port of the indie PC hit Minecraft, at E3 last year, the publisher only signed the deal a week before the announcement. Even crazier, the graphic they made for the announcement was a rushed job made the night before.

“Even the people inside Microsoft, as they were looking at it, were thinking, ‘What is that Minecraft thing and why are we putting it on stage?’ Phil Spencer, head of Microsoft Studios, told Destructoid.

A few million in sales to date.

Snagging good indies and radical ideas is one place where PlayStation Network has an edge on Xbox Live. They take on projects that are riskier and more experimental.

Based on this quote I’d say that the biggest challenge for the Xbox game library might be Microsoft itself.
