I think aside from the physical attributes of some races which may help or hurt their ability to wield certain weapon styles, racial weapons could be a cultural distinction. This would mean that in towns populated mainly by klyros and in those populated mainly by enkis, there would be weapons in the klyros and enki styles respectively. Also, these weapons would have differing shapes, sizes, and ornamentation than each other, but would still represent a certain weapon type. For example, the basic principle of a two-handed sword remains the same throughout medieval cultures. It is a sword which requires two hands and more strength to wield as it is longer and therefore heavier, and it is slower yet deals more damage than a short sword. For each race there could be an equivalent cultural variation. The weapons' stats would be very close, but the look would match the race's cultural style. This is represented in history when comparing two-handed variants from different cultural groups. There is the European longsword

, Scottish claymore

, German Zweihaender

, Japanese Katana

, Indian Khanda

, Thai dha(two-handed versions exist)

, and Chinese Wodao

. While these swords are all under the category of two-handed swords, as you can see they vary quite a bit. The most variation is seen between areas isolated from one another, obviously because they were less likely to influence each others' sword designs. The similarly isolated races of Yliakum (isolated until the portals opened) would have carried weapons with them for defense, or at least the ideas for their style of weaponry. This cultural distinction between weapons of the same type from different areas extends beyond swords into all other weapon types AFAIK. Also, some civilizations never developed steel two-handed swords at all, such as the Inca, Aztecs, Mississippians, Inuits, Aborigines, New Guineans, Pacific Islanders, Maori, and some African civilizations (so far as I know

). Therefore, some of Yliakum's races would not have their own cultural versions of longswords, such as Klyros perhaps, as their physiological make-up would not encourage the widespread use among their race of long, heavy swords. This can apply to most of the weapons, but not all. Clubs and knives have been used since the stone age fairly consistently among differing civilizations AFAIK. As some other people have already said, I don't see this being high-priority, but I think if added eventually it will increase the realism and cultural uniqueness within the game.
