Politically, we agree on 90%+ on things. Like - it would be really odd if I married a woman who didn’t believe my friends deserved basic human rights. 
But I will say we handle conflict very differently, loss very differently, anxiety very differently, fear very differently. We’re different people.  The important thing is that were able to communicate with one another. We’re supposed to understand each other’s motives, behaviors, needs. And try to anticipate them.
Ideally, we’re strong in areas the other is weak in.
As far as interests, there’s a lot of crossover. But I have specific hobbies (music production mostly), that she has no interest in. She’ll give feedback from time to time. And also, she plays piano. But we don’t play together.
I like goofy nerd shit, she likes The Bachelor. I like some gaming, she thinks it’s lame and reads in her free time. I mean, no great relationship has ever thrived based on a shared love of Star Trek or something.
So most importantly, we match well in two areas. One, we can make each other laugh. Two, we like the same foods and are adventurous eaters.
For what it’s worth, half of every live-in relationship is trying to decide what to eat next.
Quake 3 Arena and Unreal Tournament. In my opinion, these are still two of the greatest games of all time. You don’t get better because your character or weapon is better. You get better because you put in the practice. you improve your reflexes. You learn the arena. Every player starts every match on an even playing field. Every frag feels like an accomplishment.
I appreciate that modern shooters are trying to do something different with every iteration. But stuff like call of duty, overwatch, or destiny never captures that magic. In many ways, they felt more like slot machines.
Halo got close, but I always felt it was too slow. And also, I felt Tribes was the better series for online play that felt similar.
