How old do you have to be mentally to like Brofesco?

I don't really think it's an age thing. Brofresco has a very polar personality. You either like his upbeat, full-of-energy style or you absolutely hate it. There's very little middle ground.

This game feels to serious sometimes. I like his take on it :).

His audience must be in the 11-15 range I'm thinking, I don't day that as an insult, just a guess

I'm 20 and kinda like them. Granted, I generally don't like watching other people play when I could just play myself
