Rome at least got an expansion, continued to be patched ad developers showed interest in making a sequel.
All Sengoku got was PI promoting one of its mods.

There were a few of us on the dev team who wanted to do an expansion but unfortunately there wasn't enough money in it to warrant it.

One thing I loved about Sengoku when I played it some time ago is the beautiful terrain map, and the rotatable camera.

So do I And some devs really liked the focus goal of the game. Personally I'm rather proud of what I did with the introduction of firearms and the way Ikko-ikkis worked, although some of it could have been benefited from being hard-coded mechanics rather than scripted.
