You can play on dial-up without problem, KTW. The bandwidth required for the game is not high. It will be laggy, but this is not because of the connection, we all have this little problem sometimes even on dsl. Hopefully it will be fixed soon.
But, on the other hand, be sure it\'s the game you want to play. At the moment, it\'s only a pre-alpha, which doesn\'t include fighting, skills and so on. So don\'t be disappointed by a huge download. If you ask me, I will tell you it\'s worth it, anyway, you can get to know the people and be comfortable with the game
In about one month, the next release will be available, with much more features in it. If you have to pay for your connection time, maybe you will want to consider waiting a little until the next version is out, though 5 hours or so shouldn\'t be that expensive.
