"They have a cave troll." No, they have two cave trolls. I acquired a couple of cave trolls from GW's Lord of the Rings miniature line. One is plastic and the other is metal. I like the look of these models and am please with the final results.
I've been thinking about painting up an LOTR army for use as proxies in some SAGA games. I already have a full Rohan force that is ready for the field and with these trolls ready for action, I could paint up some of the goblins I have and field a second army.
I've seen some rules and boards for LOTR SAGA, but I think I might just use the SAGA boards as is and substitute LOTR models in place of the Vikings, Anglo-Danes, etc.
I would probably use these to represent hearth guard. Say each models counts as 4 men. As they take wounds that would be like loosing models in the unit. I might have to give that a try sometime.
Have you used SAGA rules for other backgrounds?
