After hearing about this game on podcasts, I finally got it on sale. It's a good strategy game, perfect for 15-20 minute bursts of play (enough time to run a mission), and with just the right level of difficulty. Controls felt intuitive to me, and I found it just challenging enough although I'm not a very good player of strategy games. I would have liked a bit more customization, but it was entertaining enough as is. I cleared the campaign but will probably go back again.
