<human>: Can you condense the text into a few key points?

Recently my friend and I got into an argument over the quality of Nintendo games (he will not be named in order to be civil). We had a debate in which he declared himself the winner of the origin of Nintendo titles. He claimed that only the good Nintendo games were made in Japan to which I pointed him to games made by Retro Studios, based in Austin, Texas, with some of their games such as Mariokart 7 (9 out of 10 on IGN, 85 our of 100 on Metacritic, and 4.6 stars out of 5 on Amazon) and Donkey Kong Country Returns (9 out of 10 on IGN, 87 on Metacritic, and 4.5 stars out of 5 on Amazon) as being good games developed outside of Japan. He said that those games do not count because they were based on franchises made in Japan and that they got the score they got because the other games they are based on. I however argued that while the idea for the games were conceived in Japan those specific games were made in the US and it was like saying the records set by the Marvel movies didn't count because they were based on preexisting comic books with a fanbase. They each achieved success based on their own merits, and while they borrow form the source material, it doesn't mean they are not considered separate from it. He disregarded my argument and said "Wii Us are for steers and queers and you don't got no horns" and they are only considered good games "because of the Nintendo fan boys that suck little Japanese dick". He also said that only people who played old Nintendo games like the new ones, he was proof as he didn't like the new Mario games. I, who only played Nintendo games since the Wii, disagreed because I love Nintendo games. He didn't debate this point but he said "well, I'm still satisfied as the winner of this debate." He then sent me his final arguments with all of his reasoning, which I will post below so you can compare this argument to mine.

Final/
<bot>: My argument is that while the ideas for Nintendo games may come from Japan, studios like Retro Studios make awesome Nintendo games outside of Japan, which still appeal to new fans as much as fans from the NES days.
