You're comparing Graal Classic to games it shouldn't be compared to, at all. I get lots of enjoyment out of Classic (and I don't even PK much at all. I don't tower or spar). I enjoy the customization, designing houses, collecting items that become rare over time, and yes, socializing with people I've met who I've gotten to know pretty well. There's actually so much to do in Classic if you're creative.
It's not for everyone, no, but just because you don't enjoy it doesn't mean that it's a faulty game. I actually downloaded Celtic Heroes recently just to give it a shot. Honestly I couldn't play it for more than 10 minutes before becoming extremely bored. I've also tried other iphone MMOs, but none of them have held my interest for more than an hour. Graal Classic is perfect for me. Yes, I have made some comments regarding the overall lack of consistent updates and new content, but I still love the game. I get bored sometimes, having played for so long, but I still enjoy it (as do 3000 other people).
