The Mega Man series has always been one of my favorite series.
I loved the lighthearted approach to Robot Designs and the brilliant level design and game play of those games.
I felt betrayed when Mega Man went to the X series, because although the game was still Mega Man I felt that the game's new art style and direction took the series in the wrong direction. The Edgy Cool look was a horrible idea, even though it was the direction all games were going. It just saddened me to see my Mega Man go that direction.
The X series almost made me give up on Mega Man...But Mega Man 8 and now Mega Man 9 seems to be heading in the right direction.
Even after so many sequels I believe that the series can evolve and add new game play to the basic formula.
Here is what I would like to see.
1)Quick Select of Weapons. Perhaps hold down B on Wii Trigger and selection wheel pops up for weapon selecting.
2)A Double Jump, or slight hover move for Mega Man. I would love this for boss battles and targeting specific weak areas. I think the hover might actually be more interesting than the double jump... Just tap Jump again and Mega Man will float for about a second or two. (He can't move while hovering)
3)I have wrestled with the desire for Mega Man to shoot diagonal for years. I have come to accept that Although it would be a natural progression of the series, that Mega Man should not naturally shoot diagonal. Instead, I think the Robot Bosses Sub-Weapons need to take more of this sort of role. Allowing for players to not just use weapons on bosses, but use their unique attributes in tough situations, like having an attack that can shoot straight up, or diagonal...or even dual shot forwards and backwards.
4)Finally, I would love bonus feature where you can actually play as the enemy Boss Robots. I don't want Mega Man to turn into the bosses or anything...but like beating the game would allow you to run through the game as different boss robots with their unique abilities and skill sets. Obviously, this could make the game have more replay value and harder as the boss robots wouldn't absorb abilities...and it would be about selecting the right robot for each level.
