I previously owned a near mint CP. Initially I though the music was great, the boxers were unique, the mini games were fun... then after about 20 plays I was bored out of my mind... Slow game, not much of a challenge. Yes, it has a high price because there were limited numbers, but I don't thing it has the bang for the buck.
Let's flash forward to the present. After wanting an NGG for the past 2 years, I finally bought one. Fun fun fun. The music can get a little annoying at times, but I can't fault it otherwise. Everyone enjoys it. Faster than I expected it to be. Shots can be a challenge, especially the hole in one.
Final answer: NGG
