This question has been a thorn in my side all my life; Do you make a long term relationship with someone who is not into the same video games as you?
Google consenus says that shared hobbies are not important compared to compatability. I agree. Compatability is the most important thing. Compatability is things like love language.. do you both express and want to receive love in the same ways (touching, gifts, service, affirmation, quality time).
How you act (naturally, giddy, happy, googly, share upsets),
what you say (inclusion in a positive future, meaningful compliments, honest "i love you"s, opening up, comfortable correcting missunderstandings, value opinion),
and what you do (listen, nod respond thoughfully; there for good times and bad, do nice things without having to ask, seek to be near when possible, allow for space when needed, understand where each is coming from, want the best and support the individual pursuits)
This all determines if you are in love by wiki how definition. But what about the fact that you want to play Red Dead Redemption 2 when it comes out, or Breath of the Wild now, or what ever your faves may be. This is very tough for me to admit and say the words "I love you". I want to fall in love with some that shares the controller with me because she wants to play as much as I do.
There are other healthier interests we share like nature, spirituality, fine cooking, movies, rubbing! I'm going to see if she'll play sports with me because that's a good replacement for video games imo. Tennis, Basketball, and anything we can "play" together, would give me a similar rush.
I'm going to talk with her about this tonight. I thought I would run it by you all first, since you must have experienced this same situation, or very least, wondered it yourself.
Update* I realize I need more bros. Told her "I love you". Thank you for the replies, you all helped me see this from other perspectives. But if I find a unicorn I'm lassoing that girl.
