I don't really think it add that much, regarding gaming I never need any thing as a supplement to enjoy my self, but other than that I do consume it occasionally, although I'm not a big fan of it, I just doesn't go along with my system, it gets me hyped then all of that fade away after a while and I feel so lazy after it, it even cost me a job once, I had a job interview early in the morning, I drove all night so I was very exhausted, trying to boost my self up I drunk a lot of it, by the time I had the interview all the hype fade away and it was just me in my unhappy state hhh.
