Dragon's Prophet...I won't beat about the bush, this has to be THE BEST MMO I have ever played, hands down.
Take Guild Wars, add the depth of WoW, but the combat system of neverwinter and TERA, the creature battling content of Pokemon, and the exploration of a console platformer, and Dragon's Prophet is basically what you get.
Dragon's Prophet doesn't nesecarily break the MMO mold, but it does manage to get every possible apsect of the MMO perfectly right.
The combat is a refreshing change of pace from the dismal, mindless grind of WoW. It's basically like Vindictus and TERA had a scaly baby. Since you're actually DOING something while in combat, merely killing mobs is enjoyable.
(And unlike TERA, Dragon's Prophet doesn't restrict your movement speed in combat, which is nice.)
Dragon's Prophet also features a more fluid questing system. Sure, there are your traditional MMO style quests, but there are also public events. (Basically skirmishes that break out from time to time in certain places.)
The game also features "surprise" quests that pop up as you journey through the world, which really contributes to making this game feel alive. (Things like rescuing travelers from bandits or doom dragons, helping wandering doctors to save a patient, picking up a rare dragon's egg, ect.) Not to mention some quests are activated by finding secret hidden things, exploring the world carefully is well rewarded.
To my great surpirse, Dragon's Prophet actually rewards exploration quite a bit, which is both odd and wonderful for an MMO.
And of course, I would be remiss if I didn't mention the dragons. Dragons can be captured, trained, battled, ridden, hatched from eggs, I meant it when I said it was like Pokemon with dragons.
And yes, you are totally free to fly your dragons wherever you want. No invisible walls. Flying is a pure joy in this game.
It also makes travelling a breeze.
And did I meantion you can have a house in this game? Yes. A FLIPPIN' HOUSE!
Or an apartment, or a secret tower, or a mansion...and you can decorate the whole thing.
THE WHOLE THING. With furnature...furnature you build with recipes you find in the world.
And the house isn't just pretty to look at, you can store stuff, hatch eggs...it's basically a house.
Add that to terretory war PVP, and GvG combat, and there probably isn't a single thing you could add to this game.
(Except perhaps more dragons.)
The story isn't nesecarily a triumph of RPG lore...the devs clearly spent almost all of their time worried about the gameplay.
Finally, I can tell the burning question on your mind. "Is it really F2P?" Yes, as a matter of fact, it is totally Free to play.
In fact, this has to be the LEAST Pay 2 Win game I have ever played.
This game features a detailed character creation system, which is entirely free.
With the exception of a few costumes, EVERYTHING in this game can be obtained without spending a single cent.
The only things this game will attempt to charge you for is extra inventory space, dragon slots, and certain costumes.
Convenience is what this game sells in its cash shop, not power or "win."
However, in addition to all that, Dragon's Prophet also features Dragon Insignias, tokens that can be obtained from daily quests which can BE USED TO PURCHASE VIRTUALLY EVERYTHING IN THE CASH SHOP.
That's right, if you don't want to pay money for something in the cash shop, you have two options.
Get it by playing the game, OR COLLECT TOKENS FROM DAILY QUESTS AND BUY IT ANYWAY.
Truly, no one has any right to call this game "pay 2 win" or "money greedy" because this game even lets you get the stuff in the cash shop by just collecting tokens.
Bear in mind, this game only recently came out of closed beta, so optimization is still a little iffy.
However, so long as you make sure you use the 64 bit version of the game, crashing and glitching is kept at a minimum.
Except for a small memory leak, the game has very few problems aside from being a little bulkier then it should be.
(Something the devs merely have yet to fix.)
Glitches that do appear are fixed with reasonable expedience. This game may have been buggy in beta, but most of those bugs stayed in beta. DP isn't finished quite yet, but technical hiccups are minimal.
Seriously though, use the 64-bit version. The 32-bit version is another matter entirely...YOU HAVE BEEN WARNED.
To sum it all up, Dragon's Prophet is a criminally overlooked, heinously underrated game that deserves the lavish praise most MMOs don't. If you're looking for a game that is truly free to play, a pure joy merely TO PLAY, with content so deep you could DROWN in it, with FREAKING DRAGONS, then this is the MMO for you.
