Great game, but it still has the GBA feeling, which kinda needs to move on now that we are playing NDS. 

User Rating: 8.5 | Mega Man Star Force: Leo DS
Megaman Star Force Leo is honestly a great game, but it still shows signs of wanting to remain a Gameboy Advance game.  The graphics are just like those out of the Megaman Battle Network series for the Gameboy Advance.  Any fan of Megaman would honestly enjoy it, playing it to the end, and it has new battle features such as the battle style being first person, viewing the battle behind the main character's head and choosing battle chips with your stylus.  Also, there are new characters to play as and if you have any of the old Megaman games, put them into the Gameboy Advance slot of the Nintendo DS and you will be able to do an extra mission, getting you a new blaster.  A good thing is that whenever you play multiplayer with some one, they become registered into your game and you can use their favorite chips.  The bad thing is that even if you play them again, their brother page does not get changed.  You have to delete their brother page and then play them in order to have it changed.  Also, if you play two different versions together and you have the forms, then you can change into the other person's forms, even though you cannot get it through playing the regular storyline.
