Rohirric is Anglo-Saxon, that is Old English. In Gondor, the noble families still used Sindarin in the Third Age.

This is a most interesting suggestion, and, quite unlike some others, also very realistic; the problem that springs to mind is the translating done by the game, which may take forever and produce one heck of a lag, and the restriced vocabulary for these languages (except Old English, where you can say anything you like with kennings, but still…) Coding may be an issue as well.
