My native language is Spanish, but I always play video games in English, and that's without exceptions. The reasons I do this is because:
1) I keep learning words in English I never knew before, so I use games as a self study method.
2) Some terms in Spanish sound weird. Hearing "Mushroom Kingdom" in Spanish is horrible, it pains me to think that younger generations will say that name in Spanish lol.
Maybe it's just a habit. When I was a kid practically all games were in English (even though I didn't understood it at the time) so maybe it's something that just sticks in my mind where I NEED to play games in English. Heck, even when I go to friend's house to play and they have the games in Spanish it just feels odd. Maybe I have a problem lol.
