I bestow upon you the honor of stupidity
this fan game is really interesting, I even play it to this day. If you don't know it, super mario bros x is a sophisticated mario game that you can play other's worlds. you can even program the game's sprites, designs, controlls in your own set of adventure. The most impressive part about it is the level editor, which could be the best thing doing in this gam, it has a lot of high capacities. This game is highly recommended by me, but I think your computer has to be windows 7 or more.
