We are now in the age of the creative sandbox games. Since the release of Minecraft, the crafting genre, the create your own game idea has been pretty popular, and has turned out in dozens of games following that idea. Minecraft has become one of the biggest succcesses in gaming history, and it will sure be as common as Tetris or Solitaire in every piece of hardware. Then we have Mario Maker, a level editor for 2D platforming brought to you by the creators of Super Mario. Looking at the dozens of roomhacks prior to its release, we can say this was a really wanted app. However, I don't think this game would have been made without the breakout success Minecraft leading the way.

But what if Mario Maker came out first?

What if this game was, per example, a GCube title? How would it affect to the crafting genre? How would it affect the platforming scene, the evolution of the console wars...?

LBP came before Minecraft and is a lot closer to Mario Maker. I don't think Mario Maker would have had an impact on the crafting genre. Platformers? Who knows, maybe a level editor would be more of a standard feature nowadays. Don't see it having a huge effect on console wars.

it had to be accessible to lots of people to became as sucessful as minecraft.
maybe on DS+wii that were well spreaded, (and if they had better online for sharing)
i think that could have changed a little the things.

Uhm. Do you mean how much it would have affected Minecraft? If so, my answer is not much.

Doubt anything note worthy would have happened

Maybe SMM gets a bit more credit, but both games are kinda their own thing, so not much would change.

Wouldn't matter.

This.

Then Super Mario Maker would have come out before Minecraft.

Don't think anything would really have happened since there were already mario level editors out but just illegal
