Well, I wouldn't want either to be frank cause idk how much of an improvement it will be loll. Cause Mario Galaxy already looks so beautiful in Dolphin with just native res + aa and if thats the only thing they improve, then no thanks and if they improve it a lot more, then it would amaze me.
Oh and I don't really care much about the 3ds remaster
That's an Emulator though. Not everyone can afford a decent gaming pc with a good video card for the graphics to be that great (it looks beautiful btw).
Also, mostly Nintendo gamers don't like remakes (including I) but SMG is an expection. It is widely considered the best 3D world platforming game of all time. And also I have no doubt in my mind a remake of such a classic would make loads of $$$ and move some Wii Us off the shelves (or N3DS for that matter).
