In a world where the dividing line between a handheld game and a Big Telly game is entirely down to personal preference, it might seem redundant to single out TRON: Catalyst for praise as being particularly good on portables. But it is. It has the feel of a really good PSP or DS era tie-in game. It’s engineered for compactness and bite-sized play sessions, with simple controls, short quests, and concise story beats. And its compactness is reflected in the price. There’s no mistaking Catalyst’s modest, indie budget. Its scope and ambition, however, are anything but modest.
