Obviously they are superior, requiring thought and only using the computer as a substitute for pen and paper.
On the other hand, they can be quite addictive, especially when they are multiplayer. The key is to make sure they don't rule your life -- that you get all your duties of state covered before you "indulge".
Recreation can be anything that truly "refreshes" or "revives" you. If you find yourself zapped of energy after a couple hours spent playing, you might want to consider alternative forms of recreation.
But if your daily life involves much physical work, for example, you might enjoy sitting down for a while and using your mind instead of your body. (I'm in the opposite situation. I'm a computer programmer, so I prefer to go outside and do physical work for part of my recreation)
That's why there's no law as to what you must do for recreation.
TV is objectively bad, however, because of the psychological/brainwashing effects, the fact that most studios are owned by the devil's henchmen, and the fact that it's passive entertainment that puts you in a hypnotic state.
But a thinking man's computer game wouldn't be in the same category.
