People still play because they simply want to. We all act as if playing Graal is "unhealthy" (excessively maybe) but it's not. It's just another game like many you've played before. Spending time on Graal is no different from watching TV, or playing a different game. Now should you do it all the time? No. Should you let it take up your schedule? Of course not! But it's a great opportunity to meet new people and waste some time if you're bored.
