Let's look at the facts:
1) Both "Platforms" have locked content at first but as you further progress into the "experience" more and more content will be unlocked.
2) Both "Platforms" Allow You To produce "stuff",which can then be seen/used by other people, which then leave their opinions about said "stuff".
3) Both "Platforms" allow one to view a wide range of stuff which he then can comment on ( Goes hand in hand with No.2 )
4) Both Platforms give you tools with which to build "Stuff" with.
5) The Green Submit/Preview/Edit... buttons oddly resemble the Warp pipes found in SMM.
Only difference is that VGChartz came almost 9 years before Super Mario Maker.
#IOI is Nintendo confirmed.
Yes, this is a joke thread :P.
