Graphically, Frontiers has been upgraded over the previous version, but not by much. Most of the improvements come in the way of characters. The models have been upgraded and benefit from a higher poly count and better textures. The same can't be said for environments, which are still very bland and blocky. The lands of Norrath have been expanded to include new regions such as the continent of Odus, the Great Unknown (which is home to the Ogres) and Plane of Sky. These areas blend in with the already existing areas, but still don't offer too much in terms of graphical 'wow'. One of the more notable aspects is that some areas have been streamlined to reduce lag. Spells aren't much to look at either and consist mostly of a few flashes and explosions.
Sound effects are scarce and repeated often. The same goes for the music. The orchestral score sounds nice, but is limited to a few tunes during battle. Otherwise, it's a very silent experience. A little more music and better sounds could have gone a long way in building a more believable online world around players.
