PlayStation 2 owners looking to take on their portable siblings can now do so with online battles of the new Yu-Gi-Oh! game, The Beginning of Destiny. According to the press release (via PSP Fanboy), the PS2 and PSP titles can do battle and, akin to other card battle titles, collect cards from cross-platform opponents otherwise unavailable in your version.
Sure, the PS2 is a last-gen console, but still one that sold almost 4 million units last year. We're hoping to see more cross-platform play between the two consoles.
