I'm going to buy 3D World, but I'm not happy about it.
I'm really not happy when ports add something major that is not accessible to owners of the original version. Feels like a fuck you to people who bought the original. It's not like I expect them to release Bowser's Fury for the Wii U, or Xenoblade Chronicles' epilogue for the Wii, but it would be nice if I had the option to buy just that extra content like I can do with Torna.
