For some reason, not every game is fitted for any level of player to play it all day long, Playing games is good for people to commute with each other, have some fun, or compete with friends for some achievements. In this situation, the game play the positive role for players. However, if a school age teenage infatuated with a game, this will cause lots of social issue, that situation is not what we are look for. Energy point system could do some effort to alleviate this situation.

In my game, limited energy point will accompany with battle / arena system. it will cost one energy point when player going to the battlefield, and at the same time, energy point will refill with the time goes by. it is better to keep a nervous battle game playing during time around 1 hours. In one word, the limitation is not for the relax playing time, it is just limited the battle time.

After all the energy point been used, player could choose quit the game, or still stay in the game, to do some relax missions, such as review the battle records, doing some upgrading stuff, or even chat with friend in the game.
