So you're saying GTA has a compelling narrative ?A game doesn't have to be linear to give a compelling narrative or an overall enjoyable experience (G-T- f**kin-A anyone???).
because that's kinda messed up lol .. GTA's story is all over the place hence the Episodes are seemingly better because they're more tightly constrained. Alan Wake hasn't had the seemingly free roam or tackle events the way you want them aspect to it from day 1 and all Remedy have said is how the story and how it's woven is the most important feature of the title.
Hence 6 months wasted trying to achieve something that ended up being not suitable for the goal they had in mind with their main focus, i-e the narrative. Doesn't mean Remedy are being lazy developers lol.
