Just got this game a few days ago. Good $12, IMHO.
It blends RTS and RPG together, oddly enough, and the combination isn't really that bad.
The plot is a simple "Stop the evil wizard" story, with... A certain movie thrown into the mix... *Cough* GROUNDHOG DAY *Cough*.
It's not exactly mindblowing or groundbreaking, but it's fun, cute, and a good way to waste a few days.
And, as an added bonus, even though it's a NIS game, no grinding or hours of worthless training required!
