I don't think variety is needed in an aliens game as long as you portray them as no developer has still done, I mean, as they actually size, and behave like. Three aliens, one of each completely different to the other, plus the always pussy facehugger, the f**king chestbuster, and well..., Cameron's queen "sigh"
Not to mention that the stupid variety seen in those two pics clearly proves these new generation aliens are oriented to the Casual Cancer and children alike.
We've got one big problem since the days of A:R, and that is Fox
