I guess when Nintendo finally goes belly up, they can do it with their heads held up because they know they didn't have to resort to cheapening their brand of games to 0.99 junk on an iOS device. Lol... I think times are changing and Nintendo isn't quick enough with the software releases. It's pretty disappointing to think that I'll buy their console/handheld just to play two kickass games every 3-4 years... It seems like Nintendo has now become a mom and pops store in the gaming industry...
actually nintendo never released as many marios and zeldas on the same generation as it did during this one.
it may feel like it's taking longer from one release to the other one, but actually they released much more software during the 5th generation then during the other ones.
we got 2 zelda games on the wii, 2 zelda games on the DS, 2 full fledged 3D mario games on the wii (and that never ever happened before) and 2 2D marios (one on the DS and one on the wii), 2 mario kart games, 2 kirby games, 2 metroid games and the launch of several new IPs (that you may like or not).
Oh and i almost forgot: SSBB!
Nintendo released a lot of software during this generation.
