I'm guessing the Suikoden VI PSP rumor is just that - a rumor. It sounds just ridiculous enough to be blatantly false, unless it's also coming to the PS2.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
