So, I'm 23, my most played game by far is the FIFA series (mostly ultimate team, but I grew up playing local multiplayer) and after that, the series I've put the most hours in competitively is the age off empires series (especially 3), after that I play a lot of "old man games" that don't require being very young to do well at them: tropico, forza, the commandos series, halo on heroic (I've never managed to beat it on legendary), the sims and action/adventure, rpg single player games, now for those "old man games" I don't expect anything to change in my enjoyment of them no matter the age, but for FIFA competitively and age of empires with its high apm, how many years do I still have of being able to enjoy them competitively before my skills deteriorate to the point I can't compete anymore? When should I start seeing a decline in my abilities? 30? 35? I expect when I'm over 30 I won't be able to play age of empires competitively anymore but will still be able to play fifa competitively a lot longer after that right?
