Not so much lost as never had to begin with.

All the backstory in Fusion was a noble experiment, a lot like free-form environments, ship upgrades, extra track elements, super weapons, and zone mode. Zone still remains the game's only strong point among the fans here. The loops and vertical drops are now possible again thanks to the MagStrip.

Unfortunately, one of the things I really liked about Fusion - the environment and the universe that was typed up for the game - went the way of the free-form and downforcey handling and ship upgrades.

And damn I'd kill to see something like the Fusion universe again. Just not as outlandish, of course.
