Well, I am making a 2x2 Martian board for my Sci-Fi. I've been pondering a 2x2 fantasy city board as well. But I am not really sure yet what I'll be making for fantasy, the nice thing about the smaller figures though is that a 2x2 board is plenty of space. Just knock the measurements down to CM instead of inches and a 2x2 board is suddenly huge.
My only issue with my elves is there are no appropriate figures for Milita, Axemen (Or swordsmen depending on your perspective), and the specialty troops. But, I asked Splintered Light about them, and they do intend to make an all female unit and corsair style units. That should give me a lot more options in the future. For now I'll just have to make do with what is available.
