I don't carry much knowledge about antiquity beyond what every person generally knows, but I can honestly say that certain units in Rome I provided an interesting experience beyond the standard infantry, missile, cavalry units that you see in virtually every TW game. I feel Berserkers and War dogs were a healthy departure from the other traditional units and were in the very least fun to control and fight against even if they aren't grounded in absolute fact compared to the well known units of the era. I'm honestly glad that they are back, in some form or another.
