1. Unlocking Katmoda 12 was like suddenly being dropped into a Futurama version of racing on the Moon: Airbrakes that work in a vacuum, open topped AG ships, a moving starfield in the background and sound in space. Bleurgh.

2. The controls aren't freely assignable. I use the square button as the accellarator in all the other Playstation and PSP Wipeout games, so why can't I do it in this one? It's annoying when I fire up WO3 or SE and my thumb still thinks the hyperthrust button is the gas pedal.

3. Analogue airbrakes and fire button: It's a nice thing to have until my left hand turns into a searing claw of raw PAIN. Fortunately Fusion supports the original PS1 digital joypad, but unfortunately the digital airbrakes only seem to work at half strength and the weapon control is stuck on maximum power with no possibility of adjustment.

4. The UK version (which I have) outputs 50Hz interlaced PAL only. On a console that is perfectly capable of outputting a 60Hz NTSC signal, in a country where most TVs are perfectly capable of displaying that signal if used with the correct cable, the lack of a 60Hz display mode (let alone progressive scan!) is absolutely unacceptable.

5. Grav stingers

6. Gravity bombs

7. Saving is disabled if you use a cheat code. I'll never forget the day (shortly after I bought Fusion) when I looked at the unlock list on Gamefaqs and thought "I have to complete 30% of this crap just to play Zone mode?!!!". Of course, it's also a good thing in that being unable to cheat to a useful degree forced me to play the game properly and in doing so realise that I actually quite like it.

8. The ice cavern on Cubiss Float 2

9. All those alternate routes at Temtesh Bay where you can fall off the edge of the track and land on another bit. If I wanted to play pinball with hoverships I'd play SNES F-Zero.

10. I like Fusion a LOT more than Pure and Pulse. That just feels a bit wrong somehow.
