Thank you for the replies.
I will mention Warlord Games rules again, there seems to be a few members that are not keen on the systems they produce but some like them so I will see if we can give them a go.
As for War in conquest, we have played them a few times now specifically for Samurai and they play a lot like Warhammer ancient with a slightly different mechanic, so far the feelings are mixed, perhaps when better Samurai specific info comes out they may play different. The feeling so far is that they seem generic and do not give a samurai feel. Also in testing dependent on the dice roles we have had Hatamoto units decimated by Ashigaru, which is fine but if it happens too many times due to a bad or good roll effect the campaign in an advers way.
Early days though. Thank you for the reccomendations I will pass them on.
