I never knew or thought the concept of Mary & Gary Sue until this moment. The first thing that got to my mind was this guy that from now on I'll call the Garyest of the Sue family.
When I first met him as a kid-teen (10-15, idk)
I absolutely loved him! It was and still is the most charming character I ever saw. Now with 26 I can totally notice how dumb or empty sometimes the story seems just to make him a Gary character, but it's not like I'm complaning honestly. It's just the way it is and the way the writter wanted to show it, I don't see any problems with that. I still love that show and I'll probably keep finding plot holes thanks to the Garyness but I don't think that's gonna make me like it anyless.
Now going from a Holywood production to an ametur porn game, the first Gary character I thought was the MC from Waifu Academy, and that one does annoys me because it's just stupidly Gary just for the holy prottection of plot armor. There was one thread here about "the smartest MC" and a lot of people mentioned him and I face palmed a little but I never understood why I did it or why would I disagree with them, until now.
As was said before, a lot of people play in an inmersive way so they would feel better with a Gary than a beta looser, it isn't like you can't have anything in the middle but the Garyest the character, the best for them. I'm not an inmersive player but that doesn't stop me from enoying characters to the fullest regardless of who they are. I guess that if my complain about WA wasn't the Gary MC then I would find another thing to complain. With a Gary or not, the game is great so it's not a big deal at the end of the day.
