This may be opening a can of worms but I hope this game has dlc support! I haven't seen a few Super Mario World enemies in this game yet like the purple dragons, Fat Hammer bros that rides on flying block, Lava Monsters, and most importantly, Charging Chuck! They are also missing Super Mario World's forest background, its key and hole short cut, p balloon, yellow and blue koopa troopas, and baby Yoshi!
They are also missing Mario 3's desert level, ice level, night level, and sky level designs. I think we're missing gulping Cheep that leap out to swallow you, and the enemies that pretend to be blocks! And where is the Angry Sun?
It would be great to see a boss pack dlc too! All 8 koopalings and the Rhinos in Super Mario World should be included! Would be great if they included the huge Bowser chase scene for NSMB Wii and Dry Bone Bowser as well!
But of course the best dlc they can offer is a portal gun from Valve's Portal and retain the flinging physics!
