I just started playing this since I got closed beta tester permission and can't go into too much detail really, but I can do some observations for those of you thinking about playing.
The game's graphics are on par with other such games like Shaiya, Rappelz, etc. If you've played those other games, you'll understand the controls well enough. The character customization is also familiar to the others, but the newest thing is the use of what is called the "fletta system". It's kinda like collecting Laks in Rappelz except you don't just turn them in for booster chips, your entire crafting and creating system is pretty much based on this. You need the stuff to upgrade, make things, power items, gain points to gain skills, etc.
I'm impressed, but again, I give a game a certain amount of time before I dismiss it. The fact that I am a beta tester though obligates me to stick with it until the end so I can help the designers in their quaries about the game. So with that said I'm not going to divulge anything furthure until I'm certain I'm capable and have enough knowledge of the game to do so.
