Well, the gameplay in MM is far more suited for lots of sidequests than OOT because of the 3 day cycle. In OOT it felt like very few things changed what happened seven years later. I've completed the game myself and also found all the masks *cough* GameFAQs *cough* and I think that it's a really good game. It will probably make it to the VC so clear up those 300 blocks that is needed and wait
The game is large, probably the best looking one on N64.
