Alright, my second review, let's get this started.

 Graphics- 8  Compared to other games on the system, this game has amazing graphics.  The blue color palette they use for Mega Man is superb, just like in the first game.

 Sound- 10  The soundtrack in this game literally blows my mind.  Especially the Dr. Wily's Castle Stage 2 theme.  To me, I think this is the best soundtrack I've heard on the Nintendo Entertainment System.

 Addictiveness- 8 Sometimes, I like backtracking through some games to see what secrets and easter eggs I can find that I missed.  And Mega Man 2 has some secret areas in its levels.

 Story- 7 The story to this game is set in the year of 200X.  I don't remember much of the story, but I know it involves Dr. Wily creating Robot Masters wreaking havoc on the world.

 Depth- 7 This game should take about a week or two to beat, if you're good enough at the game that is.

 Difficulty- 9 The difficulty in this game is extremely high.  It has many challenges in points of the game that it puts you through... except Air Man's stage that is...

 Overall Rating- 9.5  I give this game a 9.5 as my overall rating.  I enjoy this game, and am sure many others do too.  Let's just hope Capcom will try their best to make more outstanding Mega Man games in the future.

Pretty good review, got them into categories which is pretty much makes a good review, but just need a little more wording like describing a little bit more into each of the categories and it'll turn out great.

Thanks for the reply!  I'll be sure to take your advice into consideration!  

IgorBird122 : Yes, I agree!
LunarDarkness2 : Try looking into details, if it's needed, play it more times and describe more! And always review your thread, always are things that miss!

But your review isn't that bad... for a first one! Congrats and good luck for your next review!
