"There are two types of people who play Fable Heroes.
The first values his team, taking a more moralistic approach to gameplay. If you're low on health, this guy will leave the spare hearts they find for you when you're in your hour of need. This guy is a real hero!
The second is a complete jackass who only moves if it's going to benefit them in some way. This guy will leave the other three players to die so that they can't collect more gold coins and if a heart appears on the map, this guy will push past everyone and risk death to ensure his team-mates can't come back to life and steal his coin.
I'll let you decide which category I fall into."
