I read it fine, Mario Party, a casual game that gets little love on forums has outsold Bayonetta & Xenoblade, games that are arguably GOTY for 2014 & 2015 that are praised on forums.

Let's look at multiplat titles as well, Skylanders, Just Dance, Disney Infinity, Lego outsold games like Call of Duty, Assassin's Creed, Madden, FIFA, etc.

As for Xenoblade vs Xenoblade X, niche games that sell to a small fanbase.

Same to you, I don't know how anyone can look at the data and still believe Metroid would ever outsell DK on the same system.

Bigger in general. If you're implying that the Wii U is somehow a better console for Metroid to sell on despite, oh, you know, a 90 million installbase difference that's also proven to have every single Wii U game ever sell less than their Wii counterparts, then you are simply insane.

What Wii U numbers, for Metroid? Metroid isn't on the system, that's kinda why that comparison makes no sense. The only Wii U numbers that matter are again, software sales vs. their Wii counterparts, as it shows how Metroid would fare if it did release. No duh the Wii U ain't no Wii, 90 million less users have prevented 2D & 3D Mario, Mario Kart, Smash, Wii something series, DKC, etc. from coming close to their predecessors. It would obviously be the same deal for Metroid, which would put it's numbers lower than DKCTF's who is on track to outsell MP3, despite you know, 90 freaking million. I can't stress that enough.

I personally consider something a niche series when any entry in its series can only manage to sell around half a million at best and is something that's a prime 'digital only' candidate.  Franchises like Fatal Frame and a typical game developed by Nippon Ichi, Vanillaware or Atlus are what I consider niche.

In a sense though, I guess you can call Metroid (the Metorid Prime series specifically) niche since it's probably the only significant 1st party, Nintendo owned franchise that specifically targets the 13-21 year-old western male demographic and doesn't click with any of the audiences Nintendo has targeted since the 7th gen (Japanese people, kids, families and casuals).  If Metroid were a Microsoft or Sony franchise, I doubt it would meet your critera of niche because it would be right up the typical xbox/playstation owner's alley.  Also, if Nintendo diversifies their target demographics for the NX, I can see 3D Metroid making a comeback as a 2+ million seller.  But if NIntendo doubles down on the kids and casuals then I don't expect Metroid to do that well unless the NX is priced cheaply enough to be used as a secondary console.

Metroid Prime: 2.82m

Donkey Kong Jungle Beat: 1.34m

So Metroid not only outsold but more than doubled Donkey Kong on Gamecube.

Yes, i do believe that because the audience is different. Sorry that you can't understand that. I can't just keep repeating the same thing.

Lolz...

Right, like I said, if you want to believe in assumptions over the cold hard data then by all means. It makes absolutely no sense, but hey what you put your faith into isn't up to me. The audience is not different btw, only smaller, we already went over this. 

Fun online multiplayer mode could pull it off....maybe....i would hope....wouldnt hurt to try it?

MP1 on GC outselling MP3 on Wii does some harm to yours and zorg argument though. DK Returns is certainly a more family friendly franchise, which allowed it to benefit from Wiis massive base. Hell according to Wii, Dk is as popular as Zelda. No way in hell Zelda Wii u doesn't do much better than DKTF, unless NX intervenes. I can't think of any non family friendly franchises from Ninty that benefited from Wii base. Dk on Wii selling more than mp3 really doesn't prove much simply because DK as a franchise could benefit from Wii. Doesn't prove Metroid would beat Dk but the comparison would be a lot more fair on WiiU. GC Dk is a joke so that doesn't work either.

So it's not fair comparison because DKC is a more widely appealing game, lol whut? That's just why it's the bigger game. They both sold on the same 100m base, hell MP3 even had a head start. Also that's only half the argument, you didn't address the fact that all Wii U games have sold worse than their Wii counterparts.

Metroid Prime's sales are inflated though, no one at the time knew what type of game it was and many thought it was a Halo type of shooter when buying it when it was something else. This why Echoes sold less as at that point it was clear the type of game it was and DKJB outsold the latter.
