Aye. I use the term loosely, mostly in reference to a question I had a while back, being "can quake be megatextured?" The post I linked offers elaboration and context.
I find it sadly ironic that we are all so spoilt for detail, so that the images above actually start to look normal, and that you really need to look closely to see, "yes, the textures all look unique".
Nifty anyway.
I am probably becoming more and more old-school, where a few strategically placed decals let you think things are a lot more unique than they really are.
