Yeah - I just jump in and wing it.
At the risk of inviting the internet’s wrath, when people talk about the difference between serious gamers and casuals, this is the sort of thing they’re talking about.
“Serious” gaming involves a particular set of skills and interests, such that the person is willing and able to just jump into some complicated new game and figure it out. And it’s not just that “serious” gamers can do that - the point is that they want to. They enjoy it. They enjoy being lost, then slowly putting the pieces together and figuring out how things work and getting better because they’ve figured it out. And they enjoy the details - learning which skills do what and which items do what, and how it all interrelates. All that stuff isn’t some chore to be avoided - it’s a lot of the point - a lot of the reason that they (we) play games.
You talk about your inventory filling up and then just selling everything, and I can’t even imagine doing that. To me, that’s not just obviously bad strategy, but entirely missing the point - like buying ingredients to make delicious food, then bringing them home and throwing them in the garbage.
My point though is that you talk about all of that as if it’s some sort of chore.
To me, it’s a lot of the fun.
I rarely even get to the point of having to stop and weigh choices in my inventory, since every time I come across something new, I have to stop and check it out and try to figure out what it is and what it does and what sort of advantages or disadvantages it might have. I enjoy that. So all along the way, I’m figuring out what I want to or think I should keep and what I want to or think I can get rid of, and not because a finite inventory demands it, but because that’s part of the point of playing in the first place.
Broadly, you’re asking if other people actually invest the time and energy to sort out how to play complex games. I’m saying that we not only can and do, but that that’s a lot of the point. That whole process of sorting things out is a lot of the reason that we play in the first place.
