I think we're ripe for some new business models becoming mainstream.
As I see it, ads just suck. I don't just mean suck as in "I just don't like them"; they're also just terrible at accomplishing what they want to accomplish, and they're getting more terrible, and because of this there's getting to be more and more of them everywhere. I get the impression (just an impression) that society is sort of 'wising up to' ads. (Admittedly, this may be because I've grown up and have personally wised up.) I personally have not clicked on an online ad in .. it's got to be at least a few years.. and I long for a day when everyone has wised up to the point where the model falls apart. (but I'm aware that ads can affect you by other means than having you click on them, such as by planting ideas in your head or making you gradually accustomed to company or product names.)
My big complaint is simply that I just hate having every second of my day filled with people trying to sell me crap! And more than anything, I hate when content is also an ad, or disguised as ads. I loathe product placements in movies and 'sponsored by' sections that play the company's commercials. I especially loathe when huge boardroom corporations task a bunch of advertisers to come up with an ads that will appeal to an 18-25 audience, and they crack their heads together and come up with a cute, ukelele-filled, animated skit that (literally) begs you to hashtag it. I want people to stop taking culture and trying to figure out how to manipulate it to sell their crap.
Like, it seems obvious that the fact that, in order to watch a TV show, you have to spend a quarter of your time watching (or ignoring, or muting and browsing the internet during) ads, is a completely terrible user experience! Imagine if every fourth page of a novel was an ad. Or if a fourth of popular websites were ads - oh wait, they are.
It's all monstrously unpleasant. I sometimes torrent movies and TV not because I couldn't pay for them, but because even if I use the right channels, the experience is awful (among other reasons). It's crazy to me that there's not yet an option to just pay more to disable all ads on TV. I guess it was technically infeasible for a long time, but, still.
Netflix is an example of someone figuring out how to take ad-supported things and turn them into a new model. That's a good thing. (Though I suspect a huge portion of their profits comes from it being so easy to ignore their bill because you sign up once and never get notifications about it?)
Ultimately I'd like to just pay for what I consume. I like Netflix because I give them money and I get service. I give Spotify money and I get service. I wouldn't mind a service that (via browser extension or something) allowed me to specify donations per month to various sites on the Internet that I visit - so I insert 100$ a month and it gets divvied up, and in exchange I have no ads. (With the caveat that if a site shows ads anyway, or tries to bait me into reading it, or is bullshit in some other way, I can revoke their piece of my payment..).
For creative work I think patronage is an underrated business model, largely because there's a high barrier to actually giving money to something. I'd love to just be able to say, I have 50$ a month for bloggers whose blogs I read - I don't want to push to "donate via paypal" button on every site; I just want it to get sent out by virtue of my being there and liking it. [Note: what doesn't work is paying proportionally to time spent on a website. That's how you get mindless Buzzfeed clickbait everywhere. Gotta figure out something else.] Twitch figured out how to get its users to actual donate money with minimal friction and that seems to be working well for them (though they're hosting a lot more ads lately, which is very tedious).
I'd also love to see a return of the renaissance style patronage of "rich people funding artists". Seems like funding happens mostly through grants and scholarships these days, instead of people just funding specific people who can do things they want to see in the world.
For your game, if it's multiplayer, the "cosmetics cost real money' model seems to work pretty well, and avoids you being resented requiring money just to access the whole game. As does just having the game cost money up front, but, that tends to lower demand. If you want to add content to the game after it's released, I think "expansions" are treated much more favorably by the public than "DLC" is: we feel cheated when we pay half as much as the game itself and get a single, probably crappy level. It's a lot nicer to get a large chunk of content with new mechanics and new stories that isn't just a tacked-in moneymaker level like a lot of games are doing.
