The sixth and final planet is rather long. In this video, I progress further in the planet's races... In the second race, you can see an AI flaw, where Slash kept on racing on the backwards arrow, enabling the other three racers to lap him easily. At 11:35, you can see another "glitch" in the rankings, where I lapped Slash, but he was just behind me, so the game thought he finished second. Not the first time it happens in my playthrough!
I play on the hardest difficulty setting, "Warrior".
Note : I put myself a small challenge with this playthrough. Some might not consider it a challenge per se, but whatever. I decided that I will not purchase any car past the third one (out of five). So by the end of the game, I'll have a subpar car, but it won't prevent me from beating it easily... probably.
