I disagree with you, they don't "tend" to have game breaking glitches, tend is short for tendency, whish means usually. Nintendo games don't usually have game breaking glitches. It happened on rare occasions, under very specific condtions, I played Twilight Princess & when I heard of the game breaking bug, I had already past that part & since I didn't do (as most of gamers) it the intricated way that was causing the glitch, I had no problem!

Saying that Nintendo games "tend" to have game breaking glitches is a dishonest stretch IMO. They have bugs but far less than the average game IMO!

Nobody is saying they are perfect, Nintendo games too have bugs, but they try harder than anyone else to give flawless games to its customers.

It's a fact that 3rd Party companies strongharmed Nintendo out of the "Seal of Quality" policy, it's quite telling!

English isn't my native languange. I thought that tendency means there is a chance.

Back in the day when Nintendo created a boom in the industry they put a key lock system into the systems to prevent third parties from making games for competitors and control their licenses. Third parties lived in fear of screwing the pooch with Nintendo because they had them under a vice grip. The only reason people didnt bitch at Nintendo was because of their marketshare. Its because of them why Sega was forced to make so much first party just to survive. Any competition would be starved of games because Nintendo did what they did. It wasnt until the Playstation came around that Nintendo's curse was lifted from the industry (after their licensing was stopped). Nintendo was sued for breaking the anti-trust laws of America because Atari thought they were creating a monopoly.  Nintendo was not found to be monopolizing the industry but the judge saw that Nintendo should let go of their vice grip with their licensing and keylock over third parties which allowed third parties to go to their platform of choice.

There is more about Nintendo, but i'll just leave it at this.

It's alright, I'm certainly not perfect & make errors or ignore much stuff, we're all in the same boat learning from our mistakes ;)

I'm well aware of the iron fist policies that Nintendo used back in the day, they were even more ruthless with retail. While I can see that some of their pratices were abusive, you can't argue that the output of quality games was great & that the consumer was more respected than nowadays, where we are treated as beta testers, lied to, micro-transaction dry milked by broken sequel games on release, on top of that we have to pay $300 extra to play these games on-line for a period of 6 years.

Nintendo was ruthless with 3rd parties so that we could enjoy great products, Sony/MS let 3rd parties do whatever & we the consumers pay for the consequences, worse they are stepping up 3rd parties mal-practices: Sony DriveClub & MS Halo: Master Chief Collection comes to mind...

I tried, I even emphasized the bolded point just to avoid mindless arguments like these yet you still somehow missed the point. You need to take off those Nintendo goggles and stop taking everything said against nintendo as an attack on them and your way of life. 

The reason a game like tetris was broken on the PS4 actually exactly explains one of the things  devs have to deal with with the PS4/XB1 that they don't have to deal with on a Nintendo console. Please use your head for a second and not your heart, games on the PS4/XB1 are generally way more complicated than games on Nintendo. and I'm not talking about polygons here. 

What on earth are you talking about?  Are you just making stuff up?  

There is no evidence to support this quality of games that Nintendo is "responsible" for. Nintendo did not want competition, that was all. It wasnt about the quality. Nintendo basically told them if you want to thrive here is our licensing contract and you will not have room to breathe (thats all). There were plenty of crappy games keylocked on the Nintendo platform. 

I guess Nintendo wanted quality on the Nintendo Wii as well, correct? No. It had the largest shovelware library of all time for a console that had the majority of the marketshare in the last generation.

So broken games that had bundle deal with Sony is Sony fault, but when MS bundle then its Publisher fault? What kind of reason is that?

OT: They passed the certification process, and they would pass on a Nintendo system as well... the games run and none of the glitches or bugs made the games unplayable.

And to another user... The rise in complexity also makes the probability of bugs bigger.
