What about elves? The D&D elf has little of JRRT's elf in it. they are shorter and not at all special as he had therace.
Anyway, I have cleared up all such confusion in the LA RPG. Kobolds are tough and smart and good-looking in a devilish way. Hobgoblins are small and dangerous, goblins are bigger and more dangerous. Trolls are more like medieval trolls, turn to stone daylight. There are allsorts of elf-like races--alfs, lyfs, elfs, ilfs, and wylfs. Orgre are the baddest of regular giants--those of deital sorts not included, of course.
Cheers,
