My favorite Valentine so far comes from Sony in the form of a demo for Patapon 2, the rhythm-based 2D real time strategy game. If you haven't played the first Patapon, I'll repeat that since it's a lot to wrap your head around: rhythm-based 2D real time strategy game.

Patapon 2 was released last year in Japan, but Sony has been coy about when and whether it would come to the US. So even better than this sample build was the press release confirming a spring/summer 2009 release for this side of the Pacific. Here are some of the salient details:

With 200%+ more content than the original, Patapon 2 features close to a hundred missions in a variety of new vivid 2D environments. Players will outfit their Patapon army, collect resources, and grow their tribe into a devastating fighting force. Patapon 2 also presents new Patapon characters, including bird riders, robots and magicians. In this new adventure users will find even more rare Patapons and special weapons and equipment to equip and create an innumerable variety of squad combinations. Patapon 2 also introduces a fully customizable new warrior: Hero Patapon. Three additional drum beat commands have been added to enhance the robust tactical options and, of course, new songs are included for the missions, mini games and multiplayer play.
