In all honesty, I don't see what the big deal is with having a lot of cutscenes. Yes, you don't want to much, but cutscenes, at times, can look better than the gameplay.
MGs4 is like an interactive and live movie before you. But, if there are a lot of cutscenes, about 3 times the gameplay, I would understand. I will find that out next month when i get MGs4. (that is... if i stop being addicted to MKWii and GTa 4 Ps3 like i am right now.)
