It's just to... to... to... GREAT!!!
It's an awesome game, and there's nothing anybody can do to stop it. It has a great gameplay, (even if it does get repetitive), the graphics are good, and the plot is awesome. You know what's also really cool? Doing side quests to get chips and other cool things! You start off with Lan, inside the Virus Lab for a School Field Trip, on a school day. Mega Man and him are walking around, and then get an intro to virus-busting... I'll leave it off at that. Buy it and enjoy everything in this Mega Man game. It is probably the best game I've played for the GBA. So I suggest you buy it, as it will keep you entertained for hours. Just like me. So invest some money, then get it! ^__^
