Mega Man Star Force review at Gamer 2.0.
"November 11,2007 - Capcom released numerous Mega Man titles on the GBA during its heyday; many of which were games in the Battle Network series. The Mega Man Battle Network games followed Lan and his powerful netNavi Mega Man saving Dentex City from villains who used their own netNavis to infect and take over the world with various computer viruses. While the stories in each game were bizarre, they featured an intriguing action battle system that increasingly got difficult with each title. They were good, but they were just too plentiful. Now Capcom is out with a new kind of Mega Man game that sort of follows in suit with the Battle Network series, and while it has some new interesting quirks--it just doesn't do much to separate itself from the rest."
