SMB2J a rehash of super mario bros 1? You must be crazy. Where are you getting that? Would it be because it uses an identical gaming engine and the same graphics, reuses the whole system with the only changes being slight tweaks to Luigi's physics, or that it is essentially just a level hack of the original?
:P Sarcasm. Of course it's a rehash, but I love it. SMB2USA is definitely a good game though, for sure.
Speaking of the old mario games, I wish there was a way to play the SNES versions of SMB1 and lost levels with the physics of the NES ones. The SNES ones have great graphics (well great for a remake of a nes game anyway) and it actually makes me feel very involved. Unfortunately they tweaked the physics and the originals feel smoother.
The SNES remake of SMB3 kicked fucking arse though.
