It's pretty unique. The in-game idea is that immersion is key to learning languages. However, there are no real rules for or mention of languages beyond this. No list. And while that certainly isn't a must, I'm left wondering why, given Zweihänder's near-omnipresent "more is more" ethos. I assume it's for the same reason that the Demihuman races aren't given more than a few paragraphs during Character Creation: lack of implied setting, e.g., need to stay out of arm's reach of Games Workshop's IP. This stuff would be easy enough to bolt on from homebrew or GW resources, I guess. And Zweihänder's "not all demihumans are the same" deal works fine for me, anyway. But for those wanting more detailed non-human, yet playable, races, you may be left wanting.Hm. Think I'm going to have to steal that for d20 games.
