Dito.
Other than that, Morrowind is wiki-style "dialog" and not keyword-style. Oblivion has a keyword-system, but as Bethesda sucks at writing dialog, it obviously turned out to be shitty... as does the written out sentencs in Skyrim suck. So bad writing isn't depending on the used dialog system.
I personally really couldn't care less about what Wasteland 2 is using- After all, Wasteland 2 isn't Fallout. If the next Fallout game would be using a keyword-system, then I would be not happy about it. Other than that... nope.
Besides, I feel like a party-based rpg is just better off with the keyword-system. You don't have one main character who is doing the talking, anyone in the group can do it- and if then the dialog options are always the same, it makes the characters feel the same. They all talk the same, they apparently think the same, etc. etc.
