I actually kinda agree with him.
When half the game is videos in which you do nothing, then play 5 minutes and then another 30 minutes of cutscenes, it IS a form of passive entertainment.
I am a huge MGS fan but even I can't argue that, especially with MGS4 which i do not love as much as the older ones. I mean, i'm on Act 3 and the game is really boring right now.
The only reason i love MGS so much is the cutscenes. Kojima really has a talent in storytelling.
