Like Super Mario All-Stars. 

Super Smash Bros. Melee

Super Smash Bros. Brawl

Super Smash Bros. U 

All on one disc for the NX with upgraded graphics (character models, backgrounds, full 1080p). Three different play styles. Solid Snake back in. The original Smash Bros. for the N64 could also be in as a bonus. 

That would be great

That would be interesting. It would satisfy everyone who are fans of any of these games, especially those who are fans of competitive Melee and have been advocating for an upgrade version of the game. Though it would also depend on whether or not Melee will be upgraded through the US version, or the PAL version, as there are significant differences according to those who have played both versions. At least this will give Brawl a much better online experience if they are willing to revamp the online to be more bearable of an experience like Smash 4. Plus, Subspace Emissary in HD...that would be great to play again in that particular format.

I am sure everyone would hate the idea.

There would be another devastating petition demanding such a collection to be aborted.

Melee unchanged but with online is all i need

Like PlayStation all stars?

May as well throw in the original as well.

Ehh I dunno, if I wanna play the other Smash games, I'll just play the original versions.

Besides, I'm pretty sure that 90% would only play Melee, and no one would ever touch Brawl, unless they like Snake or Wolf, I guess.

Instead of putting them all in one, it would be better if they gave an option to change the physics properties being used. This way you can play with new characters using old play styles (brawl/melee/original).

Sounds good!!
