“Work smarter, not harder” is something I would have loved to tell the team at Bandai Namco behind Sword Art Online: Hollow Realization. That’s not to say there aren’t plenty of smart ideas in this action-based, single-player, faux MMO, but its tangle of gameplay systems feels like a dense pile of stuffing that never gets stitched together into a coherent whole, and its story lacks the urgency and gravity that made the anime great.
