I am 22 and I definitely notice a big difference in the first 10-15 minutes of my first match of the day, especially if I took a break that lasted longer than 1 day or if its winter and my hands are cold.
I just need that short warm-up period, before that my micro speed is significantly slower.
If I skipped like few days, the first 3 games was like my brain not even working.
I don't find this situation in action RPG.
I can still play Ghost of Tsushima / Sekiro.
But RTS? I saw a grenade throwing, brain told the hand to move, but hand doesn't do anything. I have no idea what's going on.
