It's actually perfect game design. I'd explain why it's perfect design but it seems like
MrBtongue beat me to it. The bastard. Infinitely more clever than me. I really recommend watching it. He eloquently explains how a proper and believable fictional world should be built.
Synopsis for those who care: The fundamentals of life like, eating, releasing some faecal matter when the body calls for it etc, need to be properly conveyed in some genres. In our case, we're dealing with fantasy fiction. This to establish that the fictional world operates under the same rules as real life and don't just conjure up food from nowhere by singing "I'm to sexy for my body". But more importantly, you include food, outhouses, farms etc because it's imperative when building a fictional setting for your story.
The world of your story is as much part of your story as the main plot which the main character undertakes. Fleshing it out adds credibility and grounds the world in living conditions that we can relate to thereby we have an easier time of being immersed in the story.
That's why it's perfect game design. When we're in Flotsam, we see people fishing. Fantastic, already we get a sense of how they might acquire food. We can also go to a store and buy apples and various other food. Awesome, they've set up trade to easily distribute food to those that have money. The junk food you find or buy (if you so wish though it's completely pointless) serve no real in-game purpose but the fact that you
can do it, highlights REDs incredible attention to detail, love for what they do and understanding that it's the little things, the little details that finally add up to create one big picture. The more detailed and characterized the world, the better right?
It's subtle shit like this that makes TW2 probably my favourite game ever, at least top 3. Shit like this is probably completely neglected by 95% of all who play it. They're like, "whhaaaaa? A fucking apple, seriously! What the hell, why are they wasting my time with this shit! I can't even sell it for that much!" While in reality, it's what gives the world it's authenticity and believability, since we can physically interact with the world and see that they too eat food and can be bought just like in real life. We're not
TOLD how the world works, we're
SHOWN how the world works. Fucking hell RED I love you so much I could kiss everyone of you bastards!
There's more to it but fuck, you get the general idea.
