The game has a pretty good amount of kind of easter-egg-ish dialogue when you try to do certain things (the thread they've had going for the first two games is great), but would anybody else like to see more "context" based dialogue? Every time we get the stock "that wouldn't work" or "mmm, no" responses, I wish there were more specialized things.
There are these indie adventure games "Been There Dan That" and "Time Gentlemen Please" which are heavily influenced by old Lucasarts point 'n clicks (and reference the hell out of them), and those games have an absurd amount of specific jokes for when you try to click anything on anything else. It's rare to get a stock "mmm, no" type answer.
I know something like this takes a lot of extra work, especially in a game with voice acting, but it would be an awesome touch to have more of that.
Just a thought. :D
