I've been tempted by Infinity - love the models and the rules don't seem that complex or anything. On the other hand it does require a significant amount of terrain to play; more than I'm used to with 40k so it may take me a little while to adapt to the different boards and such. I've got a 200pt list of PanOceania written up actually, focusing more on the medium and heavy infantry though maybe with a cutter added to the mix, the models are great and I've always been a fan of elite specialist teams. I've got a friend who is also doing Nomads (he's the one who got me into this game in the first place) and he's decided to theme his around the Black Hand, so it should make for some interesting matches.
