It's taken me 9 years from when I originally completed the game, to actually do the prestige mode. What I've learnt after coming back is;

1. Handling is worse thing in the world
2. The online system sucks for timed events
3. Thank goodness for YouTube so I could copy people's builds
4. My monitor has seen me mentally break down more times in 20 hours over a game more than I've seen myself break down over life itself.
