I would like to see The Elder Scrolls games' freedom of movement and freedom to do what I want, in 3rd-person adventure/rpg games like Quest for Glory series.
I would like to see the Ultima VII's level of "if you can see it, you can manipulate it" level of interactivity. If I can see a chair I should be able to sit on it or shove it against a door to block the entrance.
I always wonder what if they did all the above in a game like Quest for Glory and fill a whole CD-ROM with datas that help in realizing these possibilities. Imagine able to pick locks in those non-functional buildings in-between the Dragon's Breath bar and the grocery store. Imagine able to climb and break into the castle. Imagine more spells and able to burn the baba yaga hut with loads of fireball spells!
Sadly, nowadays, most of the DVD spaces are filled up with graphics as eye candies, rather than useful codes that enhance gameplay components. And that too it's the same old run and shoot. Sigh.
