I also used to save up every potion and usuable that I came across. I wanted to feel in control by being prepared for everything. That sounds like a fine quality to have, but it stems from a fear of not being able to handle whatever is thrown at you. It is a symptom of a lack of self confidence.

Nowadays the things that I'm most proud of in life, are things I only achieved because I jumped head first into the unknown, yet still came out on top of whatever challenge I had taken on.

Taking chances is my guess. Each weapon is a "life experience"

The basic pistol is your normal day to day. The shotgun is your night out.

But that gauss cannon, or rocket launcher are those big risk moments like asking that person out, or going to that once in a lifetime concert.

"I can't go to that concert I have work tomorrow" "But it's literally their retirement tour and you love them!" "I know but...I really need this job"

Yeah it's the responsible decision to go into work, but you're going to regret missing a day of work way less compared to missing that once in a lifetime event.

If you're saving money it's fiscally responsible not to spend it, but your peak years of health are going to be wasted "saving for your future" when you're 60 and your body isn't as capable as it used to be. So you're ruining the overall "game"(life) by trying to conserve and inducing more struggle onto yourself just to save an extra buck here and there.
