Will I regret selling?

I’ve been collecting revised 4th edition since it first came out, I have everything and I’ve kept everything pristine. Every card is sleeved and figure unpainted. But I never have time to play. I have every expansion in new condition, opened and played but sleeved so I know I have money but it’s not about that. Will I regret it after it’s gone? The artwork, the memories of 2nd edition that my bro and I used to play as kids. It just sits collecting dust. I have a Batman edition that I can part with but would I be stupid to sell the rest? Talk me out of it please.
