It's not bad, but considering how slow+dull TBS games can be, they tend to be pretty hit or miss with me toward whether I'll really invest time into playing them.
The menus all suck for touch screen, so avoid them and stick to the Dpad and buttons.
It's otherwise easy enough to jump into without much learning. I went straight into a skirmish, skipping the tutorial. I'd probably do much better if I cared enough to know more, but as-is it's possible to wing it. The menus are informative enough and the nothing about it is really obscure.
It's mostly the same game as you usually see in these. Rock-paper-scissors units, resource gathering, upgrades, fog of war tends to be a pain in the arse. But there are wi-fi menus present, so you can't really go wrong with multiplayer. Why you would want to play this instead of something like Advance Wars, however, is not something I can perceive. And with the slower pacing than AW, I do question the success people will have really sitting down to play these longer matches.
