Everyone should check out Patapon. They are giving it out for free, you have no excuses.
Its much more difficult than the second game, so if you love it enough to move on to the superior sequel the second game is a breeze given the increase in latency they give you to press a button. Much, much easier...
I was surprised, but in a good way. It would have been very bad if I had played the second game first and got used to the timing and easiness of that and checked out the first one after.
Also, a fraction of your old units move onto the second game for you to rebirth, along with some items I think. So its all good, you get a slight boost.
