I just picked up a copy of Scotia Grendel's Leviathan. This is a game I've been meaning to get for years but thanks to the excellent Leviathan War blog, I took the plunge!
I love the post apocalyptic fantasy setting and I think it has a lot of possibilities.
I pulled out some older models that might be good choices to mix in with the Levithan models. The old GW plastic orc fits in surprisingly well. The Heartbreaker figure is a bit small and the Rakham figure is a bit big but may work.

Anyway, I'm looking forward to reading the rules and getting into the world of Leviathan!
