Except no matter how many new things they added, its still Megaman 1.
For the Rockman series, of which each sequel is "more of the same", since when was being "more of the same" a proper reason not to consider something a legitimate title?
Even if a remake, you got a new game, played a new game and this time were even given the unique opportunity of putting your own creativity at work in making new content for that game. Therefore, one shouldn't act like Capcom didn't do anything for the classic series.
The fact is, that while its anew game, its not a new story
The story of the classic series has always been more of the same and never does a classic title really move the plot forward. So, what's so different from a non remake?
Not to mention, comparing the story of Rockman Rockman to the original Rockman is barely even possible. The amount of story in said remake is considerably greater, to the point that you don't need to stray very far from this forum to find people going on about the game not being canon whilst they moan about the oh so terrible retcon that has been inflicted upon them in the form of a divine smiting from their god Inafune.
Seriously, for anybody that's remotely interested in the story of the classic series, Rockman Rockman offers so much.
As for the game itself, I didn't enjoy it
Just because you didn't enjoy it, doesn't make it a terrible game.
Reviews of the game, from gaming magazines/sites and casual gamers alike dominantly praise the game as being a high quality title whose only major drawbacks are either being a remake or having the graphical style that it has.
Being a terrible game, on the other hand, implicates the game is a glitch ridden piece of trash, which Powered Up is the absolute opposite of. The only game in the entire mainstream Rockman series which comes close to the title of "terrible" is a certain overly experimental X-series title, and even for that one you'd find a whole lot people defending it to the grave.
