I did some checks on the hints and some of them do nothing while others are misleading enough to make it harder. Nevertheless a great game and helps me remember how to think in English.
For some reason people are complaining this to be hard :O The last race is easy with this tactic: Start off with a Taun + Sprint to take the lead but try to stab one before you get out of reach. Every time you see the officials when it isn't foggy try to Donate and then send them off. Every time someone is trying to pass just use Stab and if not available then Kick or Bite. You should end up taking out atleast 6 of your opponents with the Knife. You can use CYB (Catch your breath) and then take out anyone trying to pass. Not all the later on achieved upgrades are necesary. The key ones are Heroic knife, Shivving, Taunting and Donating.
I've seen several flawed trivia questions =P Like the consecutive nascar wins thing I was sure it was Jeff Gordon and with the paint by numbers it isn't palmer's paint company but japanese Non Ishida (leads to the name nonograms).
