Okay, so Mario Maker is basically the best thing ever. The E3 demo was enough to put it high on my radar for 2015 games, but the most recent trailer now has me more convinced than ever that this could be the make-your-own game I've been waiting for.
Sure, some people will say things like "LittleBigPlanet already did that" or "Mario Maker looks too simplistic." But what Mario Maker has over similar games is, well, Mario. Whereas LittleBigPlanet is a wonderful game-making tool hampered by inconsistent gameplay and awkward physics, we all know Mario, if anything else, guarantees a great sense of control. Super Mario Bros., Mario 3, Mario World and New Super Mario Bros. U are all the currently revealed aesthetics for the game, so if you can make stages based on those templates, that's something to be excited about. As for the simplicity, well, while it doesn't look like the game has the ability to make dialogue and cinematic options in the way LittleBigPlanet and its kin do, its focus on level design might be a case of less being more, allowing players to be more creative with the tools at work.
Nintendo already showed off the Super Mario Bros. and New Super Mario Bros. U aesthetics back at E3, but actually seeing the Super Mario Bros. 3 and Super Mario World visuals (and sounds!) at play has now tripled my excitement for the game. And seeing the unique ways you can manipulate traditional Mario elements (canons shooting coins!) shows that there may be a lot more to Mario Maker than we at first thought.
There are, however, two concerns I have for the game: The first is that Nintendo has yet to announce if your created stages can be shared online. Last I heard Nintendo said they were "considering" it. Consider nothing, this is one instance where online capabilities are a must. Granted, actually making and playing levels will be the core of the game, but downloading other people's stages and playing through them should be the obvious extention of that concept. The fact that Nintendo is finally making a Mario level editor is a dream come true, but not being able to share your creations with other may put a damper on the experience. Let's hope Nintendo makes the right (and obvious) choice.
The other concern I have is more of an issue of preference. I have to wonder if all of your creations will end up being standalone stages or if you can (preferably) link a few of them together. I don't suspect you'll be able to make a full-on Mario adventure (even LittleBigPlanet 2 only allowed you to link so many), but if you could make a small series of levels (a "world" if you will) to be played together, it would definitely add something to it.
But aside from those two issues, I have nothing but high hopes for Mario Maker, as it's a game I've always wanted. Sure, some insufferable hacker types will insist that emulators exist, but not everyone has the patience (or technical savvy) for such things, and hacking through a game's code just doesn't have the same appeal as having it presented to you as a kind of virtual toybox. The fact that this is an official Nintendo game will most likely ensure it will be an accessible experience, one that hopefully even those of us who don't know the first thing about programming lingo can have a go at.
Let's hope Nintendo realizes what they have going here. After all, once people worked their way around LittleBigPlanet's editing tools, it seemed like the majority of players jumped at the chance to recreate the Mushroom Kingdom. Now we have it handed to us on a silver platter.
