While researching today's other post (about Mighty Switch Force's teaser trailer), I discovered that another WayForward-developed title that I've had my eye on for some time, Mighty Flip Champs, was rather stealthily released as a PSP Mini a few months ago.
Surprisingly, said port is supposed to be a pretty good one. "It's a game that, previous to its arrival on PSP, I could only imagine as a DS game," Joystiq's JC Fletcher wrote in a recent review. "But the PSP version turns the vertical 'flipping' horizontal, and puts the two locations on the left and right side of the PSP screen. To my surprise, this arrangement works out just fine! It doesn't feel like an adaptation to a less adequate platform; it just works."
Although I'd love to add Mighty Flip Champs DX to my ever-growing collection of digital PSP games, I'm going to have to hold off on doing so until I actually have some money. Another possibility: I could wait until I buy 3DS and then purchase all three of WayForward's "Mighty" titles (Mighty Flip Champs, Mighty Milky Way and Mighty Switch Force) via that system's eShop. Decisions, decisions.
