They just don't make 'em like they used to.
There's little more important when creating an HD remake than ensuring you've at least duplicated (even better, exceeded) the functionality and feel of the original title. Apparently Robomodo didn't get the memo when creating Tony Hawk's Pro Skater HD, which represents a remix of the first and second game in the series. The HD "upgrade" is noticeably clunkier and more cumbersome, not quite matching up to the extremely fluid titles on the PlayStation, N64, Dreamcast, and Xbox.
