I have been playing Warhammer on & off since just after launch & all i can say is that this game keeps getting better & better!
It does have a few problems with lag when there are alot of people on the screen & there are some problems with population balance on some servers, just search the forums & you'll soon find a well populated server (Karak-Azgal & Karak-Norn are usually well populated).
Comparing the current state of the game to what is was like just after launch & its amazing! All the current additional content has been free & good, while the vast majority of bugs & class balancing issues have been resolved by patches. The story quests are generally quick & easy, the public quest idea works really well & the RvR (realm vs realm) side of the game is awesome!
As mentioned in other reviews there is a free trial for this game which, although limited in content, is a great way to see what this MMO has to offer. In my opinion this game is damn good & well worth a try!
Graphics 4/5 - Not great, not bad...
Sound 4/5 - Is fine for me
Gameplay 5/5 - Brilliant, always something to do
Longevity 5/5 - As with all MMO's they're always adding new material to stop people getting bored!
