There are not a lot of series left that you could argue really need representation anymore though, we're getting close to the point where characters can be added on the sole merit of being cool additions. Like, you could argue DKC and Kirby could use a 4th character, and Xenoblade warrants a 2nd one at this point, but beyond that series representation is largely in a good spot. Some would argue Zelda, but fact remains that it doesn't have any essentials that aren't in yet, even as a fan and someone who's most wanted is Skull Kid at this point I think it's still in a fine spot.We have a limited number of spots left.
There is no value in adding another Mother character.
We have the franchise and the mechanics therein represented just fine.
Anyone likely to find Mother through Smash is already going to find it.
Other fans are already clued in.
Adding more Mother is gratuitious- it does little to add to gameplay, or improve the audience of Mother, and instead just makes people who arent fans already, pissed, because it doesnt need more playable characters (and honestly, its a little selfish to ask*)
*It's fine to want a character, but to state in any way that we are in deficit of Mother material, particularly as playable characters, is flat out selfish.
TL:DR We only have a few characters this game. Let's consider more than what gets our jollies off for an hour.
I'm always just grateful for how much content Mother has at all, so I'm not ever going to argue that it needs anything more, but I don't think it'd be blasphemous if it got either an echo or a DLC newcomer (although the latter is highly unlikely due to Mother not exactly being a money maker).
