Sorry Mobius1aic I missed your post. Yes lots of studio appear to be putting huge amounts of time and money into scripts and production, but I maintain that many are losing the sight of the fact that they are game developers and not motion film production studio's. Its seems to me that games of this type and now worringly other genres also seem to be driven from the bottom up by the story, with the aim of fitting a game play structure around it. Maybe I'm old school but gameplay should be the starting point and everything follows from that.
It's "worrying" because they are still feeling out the approach. I'd say something like Heavy Rain opens up the possibility instead of limiting the experience.
I don't mind the simple platforming because it allows me to get closer to the landscape/props. I can enjoy the views better. In Heavenly Sword, sometimes I wish I could get closer to the beautiful landscapes but all I could do there was gawk in between fights. In Uncharted, this is done very well. In Enslaved, they have some rough edges but it's still more interesting than watching cutscenes throughout.
