They are few realistic reviews  of Age of Conan, and Games Radar managed to do a good one.

"Overall, AoC isn’t a bad game, but it has been over-hyped. Once you pass by the initially impressive first 20 levels, you find yourself stuck in the same monotony that plagues lesser titles working with less-promising lore and it only gets more repetitive and generic as you level up. Even the class feats and progression feel dull, with classes gaining too few abilities to ensure that making that extra push through the last of an area’s unappetizing content feels worthwhile. The Hyboria lore itself doesn’t have the luster to make a convincing world, or (more likely) hasn’t been exploited well enough; no matter how many hours we ploughed into AoC post-Tortage, it was always hard to give a shit."
