I'm not exactly sure if I would describe any gaming I do as being a learning experience... it isn't intended to be educational, so any learning that occurs is incidental. I'm sure I've realized interesting things while playing video games -perhaps something in the game clicked my thought process into just the right place for a new idea to be born. And I've certainly learned a lot about video games playing games hahaha
My favourite games tend to be Nintendo's in house games like Mario, Zelda, Pokemon, Star Fox, ect. I grew up on N64, then bought a Gamecube. I've played tonnes of games on the other consoles that I thought were really fun, but I never owned any of them, so they don't stand out as much to me. I also love real time strategy games like Age of Empires 2 and Age of Mythology -the strategy is fun, and I absolutely love exploiting the cheat codes in these games

. What I'm somewhat of a meta-gamer for lack of a better term. I'm not interested in immersion and the illusion that I am actually participating in the game world. I like understanding the mechanics of the game and exploiting them to achieve the goal of the game. Platforming games generally suit this the best. Because, for example, the world of Mario was created and designed solely to be a fun environment for a video game, everything in it is worth exploring and is part of the fun I get from video games. On the other hand, a game like GTA where the world is designed to resemble the real world is only fun for me if I am doing things that are completely impossible in real life, which essentially destroys the illusion of it being real at all and brings it in to meta-gaming territory (everyone does that in GTA though...). The strategy games are also fun because I enjoy tactical thinking and resource management, but I always reach a point in the game where I just decide to do something a bit ridiculous and spoil the game hahaha. I love Zelda because the game is super fun, the mythology is really cool, especially at face value. I love the Legend of Zelda mythology because when you look at it in depth, it makes absolutely no sense at all. There is no real continuity, it is a confusing mess an every time a new game is released it gets worse. This is because they didn't seem to really think about the over arching story until recently, so it is a clusterfuck after 25 years. I love this because the stories are really cool, but they also give plenty of space to my sort of distant, unimmersed approach to gaming.
I love video games, but I don't play them that much cause I love playing music and devote all my time to that. I probably play 3 hours a week... some weeks more, some less.
