I am personally offended by Nosfore's crapping on Diablo 2, which is a great game!
And for the idea of custom novelty items, sunglasses and so on: i have seen this in enemy territory, germans with grinch faces, allies and axis with santa hats, grenades disguised as snowballs- it is all exeptionally useless, because some servers would just hang on to the same skins forever!
This does get extremely annoying after a while, with all year christmas servers and so on. what should be doable though, should be a customizable human, heads and so on, and maybe one should be able to choose a general skin colour for the alien models, as well as some minor features.
Aliens with clothes sounds exeptinally silly, dretches with sunglasses, goons with jumpsuits, basilisks with boots, or a marauder in a full leather-gay costume (XD). I mean, so far, the goal of the alien models, have been to make them somewhat menacing, like aliens should be.
this kind of alien and cuteness does not mix altogether.
i go more for a discreete looking tattoo, that one could edit oneselves in paint or any picture program.
this should of course only be one little bit of customizable skin, in a premade size and shape, which should not be "messable"
