If you had actually bothered to read the thread instead of just accusing people, you would see that someone brought up the fact that 3D world was suppose to make the Wii U outsell that Vita, since it didn't it was a bigger failure. Someone pointed that 3D world had done that, that's it.

Both of these games are far from flops and will likely both pass 5m lifetime.

Its very common for the second release of a game to sell less than the first on a particular console.

God of War > GoW2, GoW3 > Ascension, Mario Galaxy > Galaxy 2, Gran Turismo > GT2, GT3 > GT4, Zelda > Zelda 2, Ocarina of Time > Majoras Mask, Twilight Princess > Skyward Sword.

Also with GT6 releasing at the same time as PS4/One it makes sense why initial sales are low but the game will have legs and probably be the best selling PS3 game of 2014.

As for 3D World of course install base is a major reason for low sales, but it already has 25% attach rate and will continue to sell well for the entire lifespan of Wii U.

Another thing is that both of these games will likely be bundled at some point and will become $20 Greatest Hits/Nintendo Select titles down the road. I would be very surprised if these games dont pass 5m lifetime.

This has to be the worst argument I'd ever seen. If I didn't know you were actually serious, I'd think this was a troll post. Are you seriously trying to imply that there are so many PS3's that are broken and have been traded in that the userbase gap doesn't matter.  I'm going to have to quote Mark Twain.

"It is better to remain silent and be thought a fool than to open one's mouth and remove all doubt.

wow.... way to totally only take one part of the argument way out of context.

the reason is simple.  i bought an xbox one when it came out...i wanted games to play because of the money i paid for the system so i bought games i wouldnt have purchased normally.

Mario 3d world doesn't fit that category for me because i purchased my wii u a year ago (when i bought the wii u i did the same thing by the way).  For someone who just bought a wii u though i would imagine they would buy mario 3d world for at least partly the same reason...or they would get a wii u for the game to begin with :)

mario 3d world was anything but rushed.  The game looks amazing and has a lot of replayability.  I would go as far as saying i prefer it over the 3ds mario 3d land.

Yes, it's a matter of perspective. Honestly, I find GT6 to be more next-gen than Mario 3D World. The latter is a return to the past while the former is a consolidation of its predecessor (GT5). Moreover, GT6 has higher tech than M3DW (graphics, etc.) and I don't even think that any WiiU game will be able to surpass GT6's graphics. WiiU for me is 7th gen (and I know it's a personal opinion).

Nevertheless, this thread is putting GT6 vs M3DW and people are coming here to comment over that perspective, so I guess it's not a shock for you to consider that comparison too.

That supports what I've been saying. It's about competition on a certain platform, which makes the tie ration analysis worthless in this case. The low competition on XOne made you to buy games you wouldn't buy if you had more options. The high competition on PS3 makes GT6 to be only bought by who really wants that game. The WiiU is in between these two scenarios. The fact that it doesn't fit into the XOne's category doesn't mean it's equal to the PS3.

Week after week, Mario 3D World seems unable to catch GT6. A game considered a flop has the same legs as the WiiU's protagonist.

You do not compare Nintendo games and sales to those of Xbox and PS. Nintendo always seems to be the exception to all established rules.

You do not compare a IP of a successful veteran console to new generation console....and one that isn't selling well.

GT6 is a flop "compared to the sales of GT5". This isn't rocket science. Most people understand this concept. Alone it is successful. Compared to its predessors, it flopped. Get over it.
