Fairly cookie cutter, but plenty of distinctive qualities
For Grand Fantasia, this feature is their Sprite System. However, this one does not disappoint. Sprites act as gatherers, crafters, and can even provide valuable support in battle through buffs. You can also provide them with furniture and apparel to increase their productivity slightly, as well as sometimes provide yourself with a valuable buff. Their quirky personalities will never get old as well. This system also means you will never have to go out of your way to go woodcutting. You can keep fighting or talking and the sprites will make you a millionaire.
You'll also never run out of quests, not only is the number of them impressive, but also the fact that some can be repeated (typically, these quests simply involve killing designated enemies for a given item). Also, a reputation system adds another dimension for players to work on.
There are also plenty of things to redeem for cooler objects, Dark Sprite Emblems and Sprite King Power can be turned in for reputation to where you can buy special items, and (try not to laugh at the name) Jelly Rabbit Coins can be traded in for cool prizes.
Past this, however, it plays like your typical cookie cutter MMORPG. Paladins tank, archers and squishy wizards keep their distance, clerics avoid direct combat like the flu (although the devs do throw them a bone and give the cleric class a shield).
As far as the graphics go, Grand Fantasia is an anime style graphics MMORPG, so don't expect much eye candy in the form of realistic graphics. But if you like the anime look, you won't be disappointed.
Music tracks aren't anything to write home about good or bad, though it does throw us a bone with plot. Unlike many games, while it doesn't go into a 'final confrontation with a final boss' it does carry the basis of the plot slightly farther than most games.
All in all, if you're looking for a simple MMORPG to play, but with a few distinctions, Grand Fantasia is a good choice. If you want something truly unique, try something else.
