I was interested in Mario Maker at first, but after the initial announcement, it's a pretty poor release and something Nintendo should have released generations ago. Mario Maker is nothing more than a SMB1 maker. The original Super Mario Bros. is good, but it's also the most generic of your good platformers. Playing through every stage in the game, or The Lost Levels, none of the stages really feel different, and after I started talking about the announcement, I started thinking Mario Maker isn't really worth paying more than a few dollars.
If it allowed items and mechanics used in games like Super Mario Bros. 3 or Super Mario World, then it'd be different because those games are massive upgrades compared to the original, but the original game? I'm pretty sure it won't be long before I get bored of pretty much any player created levels. I might as well download one of several romhacks if I'm interested in playing more of the first game.
