I am currently playing L.A. Noire among other games.
If you played the game you know of its quality, whether you like the genre or not. The quantity and quality of elements that make this game immersive is unbelievable. In any spot you get dozens of objects which were carefully "crafted" and succesfuly located on those scenarios to make you feel you are in that beautiful city which was post war L.A.

The thing is I am feeling guilty as I play. I sometimes feel I don't give every object, every scenario the quantity of time and worship they deserve for being so great. You enter a single scenario as a company office, a police station or a cafe, with lots of people doing their stuff, sorrounded by specific objects, and you spend there just some seconds. I mean, I know people spend a considerably quantity of time creating them. Oh, I can't help being nostalgic and remember how things were in the eighties or in the nineties...

Anyway, I was educated to feel that squandering was not good. Wasting so many ours of effort just to get that criminal as quickly enough out of the street (or just to go and play other luxurious games on my backlog) makes me some kind of criminal. I should make a responsible use of games, acknoledging developers time and effort, right?

Does this happen to you? I guess this has something to do with the years I've been gaming and the evolution we have witnessed.

Short answer: No.

The infamous 2 evil ending had me tearing

I also have to go with no.

not at all, developers know how much time people will spend on the things in their games.

Well, I can't help it.
I don't even know much of architecture. I just have some hints that help me apreciate, just a little bit. But then I'm ridding through that 1940's/1950's replica of L.A. and I'm thinking this is better than a museum or seeing some pictures in a book. I would love to have someone to guide me through it all and explain everything to me. You can actually walk through this city. I am sure students and teachers could make an excellent use of the game.

But then again, on topic, I feel guilty for not being able to appreciate so many things out there, because of time or lack of education.
It's not as common as I expected.

Not at all.
