This game was the reason I finally decided to get a PSP. With it, there were enough titles available to warrant buying one, and I couldn’t resist Patapon having seen and read about it.
Anyway. I’ve played it a bit this evening, and I’m already hooked. It doesn’t touch the analogue nub (which is good), instead pretty much relying on just two (so far) face buttons. Square makes a “pata” noise, and circle is “pon”. When you press these in the sequence pata-pata-pata-pon, your little men advance. When you press pon-pon-pata-pon, they attack. Simple! Only you have to do it in a rhythm, and they repeat it back.
Frankly, the game is fantastic. Even if I have only done two missions.
