This is a funny post as a guy, because what you said about the sofa stuff is absolutely true. Ive never thought about it, but i've never seen a male's house that has couch pillows in my entire life, and they usually start showing up when a girl moves in. Also those faux leather black couches omg haha those used to be so ubiquitous like 5-6 years ago for dudes I know. Like I said it's kind of funny because it's not really something I would think about personally, but in hindsight rings very true in my experience.
Haha. Guys just seem to love them. I guess I get the aesthetic. Black is classic and it seems like very 'adult' furniture compared to the ratty sofa most of us had going into college, but maaaaaaan they're uncomfortable and not inviting in the least. And the one thing that would make me want to (attempt to) snuggle up on them, pillows and throw cushions, are totally shunned by guys because they think they either ruin the look or are too fou-fou for men. The whole set up actually hit me months after I broke up with my long term guy of three years (over future kids, not home furnishings) that his apartment was exactly that. Stark modern with zero compromise. I had to fight to get even the smallest of throw rugs for the concrete floor and no other personal touches of my taste or comfort allowed. It wasn't apparent at the time, but now? Yeah...
Anyway, a lot of the suggestions here for say 'softening' people's home decorating style are not to try and change them or make them give up their hobbies, but to make their place more inviting to others. To show potential interests that there's room for them too, something that doesn't feel like it exists when the room is crammed with figurines, or posters, hobby paraphernalia, etc. At least, that's my take on it after dancing with four black faux leather sofas in a row.
So is only with figurines and such? I have a bookshelf of games/movies but it's because I have that many. I can't hide them somewhere. Natural light I don't get since that depends on how the apartment was built and it's crazy for someone to leave an apartment just to date someone. I also don't get the fridge thing, most people don't cook so not sure why'd they keep as bunch of food they can't cook. Shouldn't be barren though. The rest I agree with.
I think an overload/overdisplay of any hobby gives off an impression of obsessiveness or preoccupation that makes it a question in the mind of whether or not there's room for anything or anyone else in your life. While there might actually be plenty of room, it'll still potentially read the opposite to a complete stranger just getting to know you.
I do think there's a lot more leeway with books and movies, though. Neither of those were ever associated specifically with childhood like games or figurines/toys, and everyone has read a book or seen a movie, so they're also good conversation points. I think you're totally fine to display them, and as I noted in my personal preferences list, the more books out, the better.

Do you have a proper shelf or anything to show them on or is it just a board?
For natural light, if your apartment doesn't have that, there's not much you can do. I just remember a lot of guys having heavy curtains or always having it shut out in lieu of electric lights which is a damn shame.
For the fridge thing, having a variety of things on offer when someone comes over is a HUGE plus because you want them to stay longer, right? Or at the very least leave with a good impression. It's not necessarily about cooking. I just think it shows care and interest when a guy stocks his fridge for guests, which is attractive. So DO have a few kinds of drinks in the fridge and DO have more than just chips for snacks when you invite a girl or guy over. I think stuff in the fridge is also a good way to show off other interests. I had a guy whip out some Lays once, then he made a big show of "Ooooor, I do have some awesome cheeses I got at the farmer's market." Since I really like both cheese and all the things farmer's markets implies, he scored lots of points just there.
On the cooking thing, 'most people don't cook'...? That's a first for me. *_* I mean, I didn't really go nuts until my mid-20s, but even earlier than that most of my friends were pretty into it. You don't have to be a chef or anything, but I'm not exaggerating in the slightest when I say that a guy who can cook is 1000+ points on the hot scale. Just glimpsing spice racks and chopping boards is enough to make my heart palpitate.

That's a damn shame. Cooking is awesome.

Also: For people that have a ton of figurines, though, and really want to display them, just select two or three of the ones you like the most and arrange those out when an interest comes over, then put the rest in a cupboard for the night. It's just a way to gauge a reaction without pretending like your hobby doesn't exist at all. Bring them back out after and either slowly introduce more if things go well, or just skip all that and just buy a classy looking case (tall thin curio cabinets look best, IMO, because they don't monopolize space like giant rectangular cabinets) that matches the rest of your interior.
Reading H.Protagonist's post, it looks like I do, but it's not conscious. Just go over the suggested interiors in that Ikea catalog on your counter and a couple of interior design sites and mags, and base yourself on that. Just remember to add books and things to those design interiors though.
Your place looks fine. I actually think that the Lego X-Wing would make a good accent.
I agree with these two:
And as others have said, clean bathroom, clean kitchen, don't be afraid to show who you are but don't be overbearing. Do change the posters for ones the actual size of movie posters.
Haha. I'm glad it comes off as sound advice and not, why the burning need for throw pillows and spice racks?!
Looking at an Ikea catalog is a good call for some general layouts. Even if they tend to overdress their displays like crazy, they're still pretty classy. And yup yup on the other stuff~
Damn I don’t have anything in my fridge except drinks, some vegetable snacks, and condiments.
Doomed, man. Doomed.
Your place looks quite attractive, overall. Love the little touches (flowering bonsai(?), and statues) and major props for the classy and beautifully coordinated gaming display set up. You've made controllers look like art pieces. Very nice. And of course, huzzah for throw pillows. Comfort aside, that hint of red is spot on.
