This brings us to the central question: if Castle Crashers came to the PS3, why was there never an official PSP version? The PSP was a sales juggernaut, and a portable, co-op beat ‘em up seemed like a match made in heaven.
A gritty, deep combat game focused on underground brawling.

While Sony eventually embraced digital downloads, the infrastructure for indie developers was not as mature on the PSP as it was on the Xbox 360 or PlayStation 3.
