The German interview mentioned that language would play an important role in the game
So let's talk language. I've actually always wanted to see language approached in an interesting way in a CRPG, so this is good news for me. However, the questions are: how much, where, and how?
In regards to 'how much', would it be more fun or more annoying to...say, enter a major quest hub only to find out you need to either speak the local language yourself or have an NPC with you who does before you can meaningfully interact with anyone? Would it be better to have only a small number of languages, making it easier to get around, or a whole bunch, maybe livening up the environment but also making communication a pain at times? Perhaps all of the above is just too much of a hassle and language should primarily be there for flavor?
In regards to 'where', would it be better to have certain areas of the map that all speak a certain language, or just confine it to (as kinda implied in the article) uncommon dialects and forgotten languages that only come up in very specific circumstances, like Planescape: Torment and its 'language of Uyo'? Maybe there could be a group, akin to real life medieval Romani or Jews, who share a common culture/language but are spread out all over the place, as well.
And in regards to 'how', would language skill proficiency points and the like be worth pursuing? Or would it, again, be best to confine it primarily to flavor?
