Still, we're not going to label Shadow Complex's sales Achievement® (as Microsoft does) the "New Era of Downloadable Games." It takes far too much effort to produce a decent Metroidvania experience than it does a mediocre dual-stick shooter, after all.
We will, however, join in on the not-so-subtle peer pressuring. Seriously, you still haven't purchased Shadow Complex? Shame on you. (So ... just direct deposit that check, cool? Thanks Microsoft!)
