From the PlanetXbox360.com final review:
"Last week we gave you our initial impressions of THQ's virtual-shot at the UFC, now that it's time for the game to finally hit retail shelves (on Tuesday - May 19, 2009) we figured it was time to give a final verdict. Over the past couple years the Ultimate Fighting Championship (UFC) has been making moves to try and become accepted as a legitimate professional sport all around the globe. The company's head-honcho Dana White is pushing the company into all new areas and part of that is the upcoming video game from publisher THQ and experienced Japanese developer Yuke's. We have had the lucky opportunity to spend a good bit of time with the final build of UFC 2009 Undisputed and are very pleased with the sport's first true outing (we can't count the previous games as they were so horrid) into our beloved games industry. The most important aspect to get right with this game was the gameplay mechanics and overall authentic feel of the sport, without a strong physics foundation or UFC representation there is no hope for long-term franchise success."
