Just wanted to tell others about this good MMORPG for our PPC's, I have been playing it for a bit here at school and must say its quite enjoyable on our PPC6700's. I also am going to test it on my X50v and my PC.
It does require about 900MB so make sure you have some room on that 1GB or 2GB microSD card.
It is in Closed Beta ATM so be sure to fill out the Closed Beta Application. They are still getting testers.
