The only reason people think I hate on the wii U or Nintendo is because I have to come in here and point it out when unfair or incorrect information is shared.
First of all, most of these Nintendo franchises started in the 80s. Whereas something else like Halo started in 2001. Zelda started in the 80s. Gears of War started 2006. Sonic the Hedgehog came out in 1991. God of War came out in 2005.
Having an extra 20 years can definitely help something have... I dunno... 20 years worth of sales more? Especially in a 90s market that isn't full of game saturation like it is now.
The figure of 95 Mario releases definitely helps demonstrate that it occured over a 25 year period.
But let's also not forget that Nintendo pretty much owned the console race from 1983 until the launch of the PSX. Some history: The PSX's origins date back to 1988 where it was originally a joint project between Nintendo and Sony to create a CD-ROM for the Super Famicom. The PlayStation made its debut at the Consumer Electronics Show in June 1991 when Sony revealed its console, a Super Famicom with a built-in CD-ROM drive. However, a day after the announcement at CES, Nintendo announced that it would be breaking its partnership with Sony, opting to go with Philips instead but using the same technology.
The deal was broken by Nintendo after they were unable to come to an agreement on how revenue would be split between the two companies.
The PSX was eventually released in December 1994.
Now just a bunch of statistics so people can have the information at their disposal. These are global totals.
Consoles/
PSX Sales: 104.25 million
NES Sales: 61.91 million
PS2 Sales: 157.68 million
SNES Sales: 49.10 million
Xbox Sales: 24.65 million
PS3 Sales: 77.33 million
Wii Sales: 99.83 million
Xbox360 Sales: 77.31 million
Wii U Sales: 3.07 million
Games/
Halo series: 56 million
God of War series: 21.57 million
Gears of War series: 19.71
Uncharted series: 17.59 million
Mario series (between 95 different titles, over 25 years): 504.04 million
Pokemon series (between 43 different titles): 218.47
Zelda series (between 21 different titles): 70.67 million
Metroid series (between 14 different titles): 17.55 million (on par with Uncharted, despite releasing in the 80s)
The Call of Duty release schedule is somewhat similar to Mario game release schedule these days, let's take a look just for kicks.
Call of Duty series, since 2003, has had 44 game releases and 162.78 million sales
Over a period of 25 years, if they kept up the current pace, this would amount to 406.95 million
The 100 million shortage could possibly be because they haven't released Call of Duty Kart yet.
-edit-
Forgot to list Gamecube. 21.74 million sales.
Nintendo 64 -- 32.93 million sales
