MegaMan wont disappoint you.
The music is quite good and could also make you cry in some parts of the story.
The battles are very fun as you have to pick chips and try to use combos and strategies against tough enemies later on in the game. The styles gives you different advantages and different ranges of attacks which help you out and make the battles more enjoyable and more challenging if your flame and the boss is a aqua type then you could either switch to normal style or just do aqua to make it a bit more challenging.
Lots of different chips to collect and lots of bosses and if you complete the game you can try to beat the bosses again in their harder versions which could prove to be a challenge to you perhaps if the final boss wasn't enough for you.
There are secret areas for you to find and collect all the chips to unlock the gate to fighting another secret boss.
Basicly to sum it up. The game is good place to start at if you havent played megaman battle network game before and this will be a great addition for the megaman fans =) Definitely worth the money and could easily be the best of the series. 10/10
