The Jolt Network is next in line to review Mythic's Warhammer Online: Age of Reckoning, giving it an 8.7/10.
The achievements system is just one way in which Mythic has gone all-out to capture the really significant trends of gaming as well as address several of the very real issues that current MMOs suffer from, such as inadequate interfaces and poor grouping mechanics. Most importantly the developer has taken the divisive concept of player versus player and turned it into something accessible that everyone can embrace. Indeed, if you play the game and ignore the Realm versus Realm element, you'll only end up feeling short-changed and disappointed.
Ultimately that's where the dividing line between Warhammer Online and World of Warcraft can be drawn and the difference is borne out in the endgame. WHO discourages the single player mentality, but it justifies that by showing just what can be achieved when players are given a little nudge in the right direction the transition from low level content to high level content feels natural and coherent. On the other hand WoW continues to support the solo explorer right up until the level cap, after which it's a choice of assimilation or starting all over again.
