I named this thread this cause I felt making an entire thread for this topic I'm about to talk about was unnecessary but it didn't really fit anywhere else; so you can discuss other graphics things here.
how about in the minimap-- having zombies appear a different color than lemmings? like red for instance. I realize some people hardly use/care about the minimap. [said so in the thread over at Lix on reasons they removed the minimap altogether] But I personally use it a lot and think this would be a handy feature.
