GameZone recently visited THQ in Los Angeles for a preview event for Darksiders and have posted their preview.
"After six and a half hours with the single-player campaign, it's safe to say that THQ and Vigil Games have a brilliant game with which to kick start 2010. The influences from classic titles such as Metroid, Castlevania, The Legend of Zelda and Devil May Cry are easily identifiable only after a few hours of gameplay.
Speaking of longevity, the average playthrough length is said to be about 20-25 hours for a casual gamer. The reported speed test run was said to be about eight hours long. With that said, there shouldn't be any problems for gamers who are looking for a game that is worth more than a weekend rental – Darksiders is going to have enough replay value for action-adventure fans to keep coming back for more."
