I don't know if there has been a thread about the comparison of opinions on MM v.s NW, and I'm too lazy to find out. So regardless of if there was a thread, here's what I have to say:
I'm quite disappointed with NW. Not just because of the changed melee, but just it seems that NW strayed too far from MM and instead of polishing and perfecting MM, they created a different game. This game, while many enjoy it greatly, I don't. I'm probably alone here. I don't really know how else to articulate why I don't like NW as much as MM, but there just seems to me to be this weird 'random' aspect to NW that MM didn't have. There is this feeling that NW gives me that makes it seem almost unplayable and broken, while MM was very consistent.
I know I'm probably the only one who thinks this, from what I've seen everyone here seems to enjoy NW a lot. That's all I have to say for now.
