Happiness in life comes not so much from the game you're playing, but rather from whether or not you're winning at it.
You may play what could be considered a lowly game, such as being a thief, but be really good at it. You will be happy because of your success.
Or you could play a high game such as being a humanitarian, but fail at it. You will be unhappy with your failure.
Happiness comes primarily from winning at the game you've chosen.
The value and quality of the game you're playing is secondary, but does factor. Is a successful thief happy? Maybe, but not if he's a social personality.
Therefore, if you are a social personality, the game you're playing needs to have moral value in order for you to be happy.
So pick a game that has value (aka moral worth), and get really good at it. Then you will win and be happy.
