My favorite part of this game is how you can create infinite money by finding a man with a hand puppet in the city, buying the random item that he's selling below market value, and selling it back to him over and over until you have enough money to buy souvenirs for some old college professor and multiple stacks of 99 steaks for Sonic to eat to gain XP.

Sonic Unleashed is great because it's just full of useless mechanics like this. It's also terrible for the same reason.
