I had to go with the first one.. It's so damn fantastic and polished. I've probably played it the most too, although AB3D is superb to play. Those sounds of those red beasties rocks. It's definitely ripped from American Werewolf in London (someone said this in another thread too).
Why is AB SE not on there, it's a completely different game to AB, just the same tileset.
KG keeps digging....
