The big advantage of Gloranthan creatures in general was that elves did not feel like pointy eared humans in the game...
Well, that is a matter of perspective. In some ways, they will always be an aspect of humans. It is inevitable.
... and in too many games thats exactly what they are, faster better looking perhaps but basically pointy eared humnas...
They are always an aspect of humanity, so in that sense they will always be pointed-eared humans. But if that is really bad pointed-eared like Vulcans in star trek, or good pointed eared (you basically see them as another culture, the ears does not matter) is something that varies alot.
For your basic run-of-the mill D&D setting they are pretty much Vulcans in their aspect as pointed-eared-humans (although Eberron has some more intresting elves). In warhammer I have to say they are in between the two, depending on which elves you are talking about. The basic Wood elves certainly are the most boring of the bunch, and I would give them a 6/10 on the Pointed-Ear scale. High elves are a bit more intresting, but that is mostly because they have inherited a part of the Melnibonèan culture as I see it. The same goes for druchii. Both High elves and druchii actually feels like a culture of their own, so they are a bit different from most RPG elves. But without problems they could have been developed a bit further to distinguish themselves (without changing their looks).
Few of the Glorantha races felt that way as they had there own way of the world, there own gods etc.
That just proves one of the points I have been trying to make. It is the culture, the religions etc. that makes a race distinct. Just changing the appearance to be "original" or "cool" does not make an elf (or a dwarf, or whatever). It is better to develop the cultural aspect of the race, than their appearance. Though to some extent, apperance should reflect their culture, as long as it does not become rediculous.
And the last part is actually something that I have seen Glorantha excell at. It has had a vast host of creatures that just feel plain rediculous (just like D&D). It might be that I have the RQ3 Deluxe box, with the RQ Bestiary, and the images there, to have formed my opionion. But most of the creatures therein, I would not even consider using in a campaign setting. Many feels like they have escaped from a bad scifi movie out of the 50's and 60's (same actually goes for D&D).
The best thing about Glorantha is that its not a normal fantasy world, it has its own feel, its own quirks and no hobbits, sorry halflings.....
It is both a strength and a weakness.
Too much uniqueness and it ends up being not very unique at all, just bizarre. From the time I GMed RQ in Glorantha (which basically was with the RQ3 Deluxe box and RQ Bestiary only), the strength I see in it is the extent it draws upon historical sources for it's mythology, and through that actually becomes rather generic fantasy, in the sense that it draws upon our classical heroic tales.
It is very much a setting (as I have percieved it) in the sense of the tales of the Illiad etc.
