From NextGen Player:
"With the launch of PS3 firmware update 2.40 on July 2, Sony has officially launched their own gamer reward system to compete with Microsoft's well entrenched Achievement system. Microsoft was the first the out of the gate, and has had two and a half years to refine and improve their product. With this experience under their belt, is Microsoft's Achievement offering better than their rival's Trophy system? Or has the extra time allowed Sony to develop a superior reward system?
In part 1 of our feature article, NextGen Player will examine the reasons why Achievements are better to Trophies. Next week, in part 2 we will examine the reasons why Trophies are better than Achievements."
