I was in my local game store (Just by Chance), debating with a friend. I play WHFB and was really longing for something else, and he suggested Warmachines. I had to admit I liked the look of them a lot better.
When I got to the register the clerk was really keen to hook me up with the local play group, and was also quite happy with my decision (it was, in her opinion, a better game). So I've got the main book and looking forward to crushing skulls and rending iron!
