If you play Drugwars for profit/money you'll not gonna enjoy in my own point of view.
Spending your free time with kids is like spending your free time playing Drugwars.
After playing with kids, sometimes a surprise of good/bad news will follow.
Playing Drugwars seems like the same, surprises will follow good/bad.
But the goal is always achieved, to enjoy.
I spend time playing Drugwars for free like what I did playing with Kids for free.
Rewards for me are surprises added to my enjoyment in playing.
