Best of Series in terms of Storyline
Gameplay: The original GW gives the player a deep PvE and PvP gameplay inside an easy to us interface. This one is no different. The addition of the Heroes give you extra tactical control over your fights and it is now easier to control their actions. The Dervish (have not played the Paragon yet) plays very well and have cool armour to boot. The entire game is much longer than Factions, althought I feel that some of the missions are quite drawn out & can be shortened a bit.
Graphics & Sound: Still the same old graphics (not that it was bad in the first place). The art of Nightfall is pretty good though, the Arabian Nights theme suits this game. Sound as usual is fantastic, with a sweeping score that never gets old.
Peeves: Bugs, bugs & more bugs. One has to wonder if the 6 mths period to rush games out is too short. A bug (it better be a bug Anet!!!) that prevents the player from capping Avatar of Lyssa if the player has done a certain mission. A bug that mixes up your choice when choosing the mesmer & warrior hero. A bug in a certain mission that teleports half the tea, away just when you are about to hit the final boss. Geez Anet, fix them already. But overall, in spite of all teh bugs, it is still pretty easy to recommend this game to all users. After all bugs can be fixed (but pls fix them fast).
