Value things that can be gotten out of computer games:

• community
• feelings of victory
• feelings of adventure
• feelings of learning (for learning games)
• feelings of relaxation
• feelings of pain

computer games can be good for getting things like the sense of community or victory, but on the downside they occupy time and sometimes do other things i.e. become addictive.

For simulating victory-feels; yes.

Ask yourself -

1. what are you getting out of games,
2. at what cost?
3. what do you want to be getting out of games?
4. and what do you want to be getting out of those expenses?

You should weigh up the costs and the benefits. Do you need some of those benefits? Are you willing to incur some costs? And decide where the optimum game-time is. (also check again at a different time and re-evaluate regularly)

There's been some actual research into that, this talk is a good summary.
