I bought it in the PS Store (download) and it's fun... it starts in 1985 or so (not 1989 as the timeline says) but then it's just a collection of challenges that you need to finish - looks like Tron is training you -.
The challenges are: shooting aboard a Recognizer (hardest part so far), lightcycle race, lightcycle arena (modern), lightcycle arena (classic: 90 degree turns ony), tank battle and disc wars. I might be missing some other 3 that I can't remember right now.
In a way it reminds me of the Battle Mode and Mini-games that came with Tron 2.0: Killer App for the Gameboy, but with better graphics
