Games like Tactics Orge, Final Fantasy 12, Vagrant Story have the depth of a book in their design. a lot of the time art design can do a lot for storytelling. many games can go a lot deeper than films and in some cases books. i thought Heavenly Sword was a great game. but it needed a lot more variety in its gameplay. i think they couldve done that with a sequel.
Enslaved was an excellent game. a well told story, in terms of voice acting, script writing and performance capture. the cloud thing was awesome! sadly i feel like the game required more replay value. theres also a book which i have 'The Terresect' that i havent got round to reading yet, but i would like to eventually.
anyway this information is obvious. the reason any developer goes multiplatform is for more success.
