In most cases, I am not much of a completionist collector. I can play Genshin Impact and never be bothered that I don't have all characters, or play World of Tanks and not mind that I don't have all the tanks. But there are exceptions, for example I buy all 5th edition D&D books published by WotC, both rulebooks and adventure modules. In fact I even buy them twice, once physical, and once digital, on D&D Beyond.

The large majority of my spending goes to straight up purchases. I buy D&D books, I buy PC games (mostly on Steam), I buy Switch game cartridges, I buy board games (mostly on Amazon), and those are all straight buy to own kind of deals. Well, technically you never own video games, you just own a license to use them, but its a perpetual license.

Having said that, I am less allergic to buying virtual stuff in games than some of my readers. I rarely play a Free2Play game for free, I usually spend at least some money on it. Most games have some sort of starter pack or VIP level system which makes it that early purchases give you a lot of advantages. I don't usually go overboard and become a "whale", because the more you buy, the more the returns are diminishing. But I figure that a lot of games I like wouldn't exist if nobody would spend money on them, and if I can afford to spend some, it enables other people to play for free.

However, if I spend money on something, I want to get something out of it. I'm selfish that way. I wouldn't spend money on a game when that spending would be a donation, or just buy me some cosmetic effect. And I am downright mean when it comes to content creators on the internet: I'll use my free Twitch subscription or other free means of rewarding a content creator ("click the subscribe button!"), but I rarely pull out my wallet and donate or sponsor somebody on Patreon. Maybe that is because of my own meagre efforts of monetization of my content, and the even more meagre response to it. I don't really get the whole donation economy around some of the more popular streamers and influencers. For me, putting content on the internet is a form of self-expression; if I do it for free, why should I finance somebody else for what is essentially the same thing, just more popular than me? I can understand a level of donation that for example finances a content creators game purchases, so that he isn't depending on freebies from the industry. But financing an influencer's "full time job" or even luxury in some extreme cases, I can't see an argument for.
