I like MMA, or to the uneducated, the UFC. MMA is a sport that has had a short time on this earth, but has had a long history through the different martial arts assocatied with it.
Japan and the U.S. are the two biggest players in the MMA scene. With the UFC the powerhouse in the U.S. and Dream and WVR (World Victory Road) as the main promotions in Japan. UFC fighters are deeper in talent than the fighters in Japan, but one thing I know, the Japanese promotion have better poster designs.
Based on design alone, I would rather go to the Dream event. The DREAM poster just has a more warrior spirit feel to it. Unfortunately, there is a whole ocean and a tough economic times to fulfill that.
