I have a stack of the late Bronze Age Foundry figures and by chance had them out for a game last night, using Lion Rampant to see if they work, I will be watching this thread with interest. Happy sticking with my mid to late Bronze age but more figures and different rules are very appealing.
I have found that there are figures we can use if we are a bit creative. I also picked up some of the Warlord Bronze Age figures to use as slingers as they are very generic. I also picked the odd semi naked figure from Trojan ranges to bulk forces out given how limited the Foundry range is. Some of the nicer figures I have used are Perry Plastic sudanese, picking the figures that have kilts but not too thickly bunched around the waste, add a javelin and a little leather buckler and a European looking head and they look the business, especially if you mix them with the Foundry ones.
