This. Game. Is. Hard.
Ok so I've managed to get all 232 stars in Grand Tour mode and I've beaten all the Grand Prix's in expert including mirror mode. I'm working my way to getting the triple star license and I tell ya... those expert ghosts on time trials are killing me!
I must have spent 45 minutes on that Shinobi level because the ghost drove so perfectly it was hard to make any headway. After I beat it I checked the leaderboard and its like only 30-40 other people managed to beat it too. The Panzer Dragoon track was crazy too because 80% of it is in the air and you have to chain all these risk-boosts together to get ahead of the ghost.
Can you imagine a kid getting this as a gift because their parents looked at the box and thought it would be a fun cheerful game then for the lifetime of the game the kid can't unlock half the characters.
I'm having fun in the online mode. Except for the quitters, this one guy was consistently beating me in 4 races and before I manage to win the 5th one he quits on me; honestly though I felt a little satisfied for making him quit.
