Great game. The only way to make it better is a mouse and keyboard.
A word of warning - PLAY THE DEMO BEFORE YOU BUY. The controls take a little getting used to and the lack of hot keys can make micro managing an issue. Which brings me to my only issue with it. Without a keyboard and mouse micromanaging your units when the combat gets hectic is nearly impossible. I would love to see a patch for keyboard/mouse interface. Because throughout the campaign I was really missing my hot keys.
It is what it is. It's not for everyone but worth giving a try and if you like it - great. See you online.
