I played the demo and I didn't find it anything spectacular. It's like MGS4 on the PSP.
At least its better than the last PSP MGS game. That was total crap. The controls sucked, the gameplay sucked and the storyline? WHAT storyline? it just sucked. They cant make this one worse.
I hope they fix up all the problems they have in the demo then add good gameplay to it and less story. I want to play a game not watch a movie.
That was the problem with MGS4, too many bloody movies!!!
I liked the storyline in MGS: PO it filled a lot of gaps for me, and I loved the comic book style cutscenes, the controls I thought were more than good, the maps were just about the right size for a portable game.... well I just disagree with everything you said.
I will say that in order to be more popular with the masses MGS4 probably could have done with less cutscenes, but I like it just fine as it is. Just the other day I spent about 2 hours reading through the MGS database, so I'm just all for the story of the series.
