Catventurer: GOG is a business and is going to preserve what customers are actually purchasing regardless of how Patrons decide to vote, so I think that letting them vote on anything is to give them the illusion that they're getting something for their money.
The patrons could decide to go full on FAFO and vote unanimously for something super niche (like VR games) or something that would be super polarizing (like online multiplayer games with no offline or single-player) just to see what GOG would do about it - GOG is still going to preserve things that the majority of customers are actually buying.
Around three years ago, GOG announced that they were going to add more online‑only titles. The only one they had been offering was Wolfenstein: ET. Perhaps they abandoned this plan, or perhaps they would add more, provided patrons showed an interest if asked.
Patrons can request whatever they wish, but GOG makes it clear that they may consider unsolicited suggestions, wishes, or ideas-but whether they do is on them. Patrons can cast votes in official polls and may be asked for their opinions on what they would like, but their subscription fees do not grant them any special rights or power to make decisions.
Some subscribers joining the official Discord came with a false idea what they were paying for, and what they would get in return, active involvement in a decision making processes, exclusive access to GOG staff, a true voting power on important matters. If they had read the Patron FAQ and Terms of Service they would have realized, that all they would get is a badge on games entering the program from the point their subscription enters into affect, access to the Discord and some videos. Allowing them to vote on games or a genre started only just recently. Being able to access the DC has its intrinsic value now.
GOG may have to come up with ways to increase subscriber numbers, they appear to be stagnating, and there are numerous ways to achieve this goal, as I've suggested in my previous reply to Sargon, but it would be more important to offer something to their current subscribers to retain them, as well as things to offer attracting new ones.
I would still not consider subscribing to the program becase my opinion about it is still the same. As long as GOG isn't fixing all of the technical issues, as long as they are not implementing functions, every other store/rental platform has had for more than 20 years, to improve the overall shopping experience, the introduction of a working tag-system and more. The good news is that they are working very hard to change and improve store, client, and website, communication with their customers, and maybe-at a later date, they will also tackle the forum and all of its specific issues. Once those essentials have been covered, most of the issues fixed, and additional functional and optional improvements becoming available, I may sign up. The ultimate decision will depend on the incentives they'll have to offer me, because what they are doing with the program is still the same as they did since their inception, 26 years ago.
