Geo Stelar is slowly becoming suicidal, thinking no one loves him and he can never trust anyone after his father's demise. So, he goes to his favorite Star-Gazing point and a "FM-ian" senses Geo's loneliness and "Waves" into his Transfer(It's like a PET except no Jack-In stuff). So, Mega(Original Name is Omega-Xis[Oh-Meh-Gah-Sis]) informs Geo that the FM King wants to destroy Earth, but to do that he needs the Andromeda Key(Which Mega stole) so he sends his FM soldiers to try and get the Key from Mega any way possible.

Storyline

It was sort of confusing at first, but then the storyline becomes so much more intriguing.

Gameplay

If you just started this after playing Battle Network, you will feel totally alien. The battle system is now 3-D so you will end up on the bottom screen. If you tap down on the D-Pad, you will create a Lock-On so when you use a chip, it will position you in front of the Virus and use the chip(Which makes sword combos so much easier). Also, they removed the Letter thing, meaning Program Advances don't exist anymore, but you can do something called a "B-Combo" or Best Combo. It's like a program advance, but can't be used unless you make one(Which is during a boss battle[Like WolfWoods battle]) and then buy the Combo in Card form for 3k Zenni.
The battle system is so much easier and is a lot more fun but challenging as well.

Mini-games

You get "Navi" chips which allow you to use their special things. For example, PropellerMan Card allows you to control an RC airplane during Side-Quests or part of the storyline. You get Navi Cards and they are really fun most of the time.
Side-Quests are also Mini-Games, because you need to "Wave In" into a person's transfer, read their personal information, then offer to help them. Lots of times, you need to show your Navi cards or trade battle cards. But there are three Quiz Masters so it's best to do these quests.
Final "Mini-Game" is the Megaman crossover with the old Battle Network games. You put a cartridge of one of the Battle Network games in Slot-2 and then go to the Dog house, you will encounter a Blue orb who says "That's important Sci Lab data" and you offer to help the orb. The rest you find out yourself.

Appeal

I loved the new Brother-Band system, that has to be one of the best appeals in this game. Making a Brother-Band with your friends and then being able to use their favorite chips and transform into their version Admin(If they have a different version from you).
I also loved the new 3D battle because it was so much more fun and always a challenge.

Controls

Getting used to them takes no time at all. It's the Target system that alters your strategies making the battling a bit tougher. Otherwise, just like a normal MMBN game.

Overall

Megaman Star Force is a good series if you are an old time Megaman Battle Network fan or are a brand new Megaman fan. It has many fun things to do, and the wireless features can keep you playing for hours.
I recommend this game for people at least 10 and up, mainly because of Geo being an emo douche and because they probably wouldn't get the storyline because of Geo being such an emo douche.
