I think it is pretty well known around these parts and fondly remembered.
But I often think that the only one AvP concept to come close is the original. I don't like the almost complete lack of story in the original but I do care much more for the balancing.
Preds were super tough with advanced slow repeating weaponry, the humans were the weakest and slowest with very high repeating weaponry, the the Alien were the fastest with the strength to rend humans to shreds in seconds.
This is similar to the way AvP2 was balanced except the Alien speed was greatly reduced thus making them the most vulnerable class in multiplay.
I was the prae just so I could tank damage and get in close.
I PREFER AvP2 by a wide margin, but the idea behind the species was better in the original (which I'm still amazed was completely overlooked in AvP2010 by Rebellion)
