ArenaNet shows true abilities of this serie. This game is well worth the money.
The game brings in two new professions -- the holy Dervish and motivating Paragon. The dervishes are sandmen chosen by the gods. They pray to the wind and earth for blessings, then they unleash the fury of their scythe to defeat their enemies. They can also become avatars of the gods for a period of time. Each of five avatars has its own set of "pros" and "cons". The Paragon motivates the whole party using his wide range of shouts -- ones provide healing and energy, ones weaken their enemies in some way by making them more vulnerable to some attacks and attacks with a spear.
Graphics are the best in the game as of 29th of August. The coming Eye of the North expansion will be of course prettier than the present one.
Sound is very good. The voice acting is well cast, but the whole game lacks that unique feeling. Music is great, the well-known composer Jeremy Soule did a fantastic job with this one.
Gameplay is as good as ever, this time ArenaNet added heroes -- a set of personal henchmen NPCs which you must equip and choose their skills like with your own character. The authors also added new type of gameplay for PvP involving heroes. These arenas are called Hero Battles. It is where two players fight with each other while using the set of three Heroes. In April 29th, ArenaNet added the Hard Mode to provide bigger challenge for those, who completed each of the campaigns by simply changing the mobs' level and skills. Some of the bosses now carry two elite skills with them! They also have a chance of dropping a "book". These books provide your character with skills and are worth enormous money. A few more guild halls have been added to suit the Egyptian looks of the campaign, but nothing(!?) more has been added.
In fact, I find GW:N very entertaining, and I'm guessing you will too! Go ahead, give it a try!
