Two must-buy titles grace the PSN update this week. First up, for PS3, the Castle Crashers are finally set to rescue some princesses using classic 2D brawlin' -- you've put $15 aside for it, haven't you?

Also, PSP-owning fans of strategy titles shouldn't miss out on Valkyria Chronicles 2, the worthy follow-up to the overlooked PS3 gem.
