Basically, it's as good as MMO's get...so you won't be disappointed. But, if you're a big WoW guy (or maybe some other MMO), I can't guarantee you'll like this better. It's definitely its own game and it plays great and looks even better. There are some things I don't really like:

-When you die, you resurrect at an obelisk that you bind to (which costs money). Which means if you forgot/couldn't afford to bind to an obelisk nearest your location, you'll have to trudge back there or pay to fly/teleport back there. Very inconvenient, especially since EVERYTHING costs a lot in this game. Which wouldn't be a huge deal if it wasn't for the second problem.

-Auction house limit. In WoW, you can throw down about as many items as you want (if I remember correctly) and just wait for people to take them off your hands and basically earn an income even while you're logged off. In this game, you have a limit of 10 items. That means that you have to prioritize what will sell and what will bring in the most money.

-Which is the last thing about this game. Shit is EXPENSIVE. In WoW, at around level 20, you can get your basic weapon for less than a gold at a shop (if I recall). In this game, it costs around 30,000 Kinah (roughly 3 gold). For those who don't play WoW, that may not sound like much, but WoW utilizes Copper, Silver, and Gold (100 goes into each). So 100 copper is 1 silver. 100 silver is 1 gold or 10,000 copper. Kinah is pretty much the same as copper. If not more valuable. The only income is from quests (only a few thousand Kinah per quest which is lame) or selling miscellaneous items (you know, things like "Broken Claws" or "Tattered Hide" or "Bird Eye" or whatever random item each creature drops). These things tend to bring in a lot of Kinah, so if you're ever poor, you can always grind for both EXP and random items to sell.

Those are really the only two big flaws I've found. The game gets VERY hard around level 15 or so. The quests demand groups. I usually don't like grouping with non-friends. You never know the other person's agenda, what quests they're doing, how good they are, etc. So basically, I tend to solo my MMO's (and it works great in all that I've played). In this one, when it says it's a level 17 quest, that could very well mean that you have to have a group of 15-18 level characters fulfilling most roles (healer, DPS, tank, etc). Today, I actually broke down and grouped with some people in an area that is literally impossible to solo (I'm level 21 and I couldn't get past the bridge into the area for level 18 and lower quests). It turned out great and everyone did a great job (even our healer who was a total n00b--more than me).

So...yeah. If you're huge into WoW, I might not suggest it just because you WILL hate the things I mentioned. To the point of hating the game. If you're used to playing other MMO's or you're open minded, it's definitely worth a try, but maybe not worth the $50 and $15 monthly fee. You get your first month free which can serve as a trial run, but $50 is a lot for a one month trial. It all depends on what your financial status is, really. Personally, this is my favorite MMO. It has that polished feel of WoW with the Korean grindfest feel to it (not that it's a grindfest--no really, it's not--but I love Korean MMO's like 12Sky and Perfect World). For me, this is an awesome game.

There is no downloadable demo/trial of the game, but there IS a refer a friend option (should you have a friend--this guy--who has the game). The only issue is that it's a 5 hour trial (that may include install/download/setup time--I don't know) with a level cap of 7. Not only does this rush your play time (and essentially demand that your entire trial is in one sitting), but it rushes you to a stupid-ass level. At 10, you "ascend" and get your wings (basically the gimmick this game has to try and look unique). And wings are definitely fun and become more and more important in the game as you progress. Denying someone the option to ascend in their trial is like giving a WoW trial saying, "You can play elves in this game, but you can only play an orc in the trial". Kinda stupid.
