I used to play this game alot last year. Its a nifty little game, but it looses its touch pretty quickly. I played it from beta 1 to just till the end of summer of last year.
It plays just like diablo (point and click to move and attack). When you level, you choose a spell to level up and add some kill points. You need to hotkey spells and skills and items just to use them. The job system is alright. You start as a novice, work your way up to the next set, then work even more to get to the secondary jobs. Its pretty basic. The world really ain't to big compared to other mmo games, you could explore it all in a day or two (considering if you can survive in level 50 maps). And some of the crowded maps are pretty laggy, even on cable and dsl. The graphics are, meh. The sprites for the characters are done nicely though (they remind me of final fantasy tactics).
If you get it to work right for you, it'll be loads of fun. The only major downside is the level grind. When your trying to get from job level 30 to 40, your going to be really bored and/or irritable. In the end it really depends on your prefrences to games. I found it pretty fun, but I just kind of grew out of it.
Edit: Fixed a poorly writen setence.
