I was wondeing since while playing osu! that you have to react quickly to get from place to place as well as memorize as you replay the same beatmaps, I've noticed it was simular to playing an action game. So would playing Osu on a regular basis make you react faster and improve your memory thus making you smarter, or would nothing happen?
I have not noticed any sort of improvement and instead have noticed that my memory has gotten way worse due to how repetitive everything in the game is. My sense of time is also pretty borked up. Sometimes I get surprised when I notice that some score I did is over 2 years old when it feels like last week.
There's no variety, which is something that I think would improve how your brain works. It's just the same thing repeated over and over.
