So I had a thought about those "short summary" dialogue choices that are bothering some folks (the whole "but I want to know exactly what I'm going to say" thing, etc).
I'm wondering if it's at least partially a by-product of the new Dynamic Dialogue thing (rather than "copying Bioware").
It occurred to me that if you can reply to someone saying something by just aiming your cursor over at them (as you and they are still moving around), it would be problematic to have to quickly read through all the full lines to pick something. Ditto with having a scrollbox with a dozen options.
For the "dynamic" thing to work as envisioned, you need to be able to glance over, pick something relatively quickly, and get back on with what you were doing. Hence, only a few options tied to action buttons (have we seen a PC version of the dialogue interface yet?), and quick summaries of what each option is.
Note that I'm not saying this is better or not. Just that the limited reply options & short text summaries may have been a by-product/consequence of the basic concept itself. (Personally, I'd prefer dialogue to still work like in FO3 - the whole Dynamic Dialogue! Talk while you walk! thing seems really awkward to me.... I've got no problems being locked into a dialogue window, it's how I've been playing cRPGs for 30 years...)
