I think it would be a good idea to have different languages for the different races of the game. Of course there would be a common language avaliable to all (english(?)) but if for example a dwarf -player choses to speak dwarven ,only those players with the dwarven language will be able to see what he just said(the other players will see dwarvish- \"rack balin rond pock..\"-). Maybe there should be an option to learn languages from PCs who know the language (and have the teacher job) for a price , or even a quest, depending on the PC teacher. Also it would be good to limit the maximum number of languages a player can learn depending on his inteligence. I think this would help to strengthen the bonds between players of the same race ,or even add to the role-playing f the races (eg : responce of an Elf PC when a dwarf asks him to teach him elvish: -\" I will never teach our noble language to one so short and filthy as a dwarf...\"  )


 hope you like my idea, so the developers will put it in the game...
