It was inevitable that gamers would compare Playstation 3 trophies to the Xbox 360's achievements. While it's true that both reward systems add a considerable amount of replayability to games, it's still unclear which is superior. The main thing that Xbox 360 fans can boast is that achievements are mandatory for every game available on the Xbox 360 and it has been that way since the launch of the system. It is a shame that the trophy system Sony implemented in many of its games were not available at launch and was not mandatory throughout most of 2008. Hopefully, trophy support becomes mandatory in 2009, so that gamers aren't torn between buying games based on whether or not they support trophies. Regardless of which was around longer, trophies and achievements are very similar, and are in direct competition for gamers attention. Here are the reasons why trophies should motivate more gamers to collect them all rather than collecting achievement points.
