surfer1260: - Workshop (this is absolutely mandatory if you want to attract more customers to the store)
AB2012: It's 100% guaranteed that if GOG tried to introduce "GOG Workshop" they'll gate it behind Galaxy. Personally I think locking mods to 3rd party stores that played zero part in creating them has always been completely the wrong direction. Want Mod X? That's only on store A's workshop but not B or C and requires store A's variant of the game. Want Mod Y? That's only on store B's workshop but not A or C and requires store B's variant of the game. Want Mod Z? That's only on store C's workshop but not A or C and requires store C's variant of the game. What an absolute mess... That Valve took a huge 'walled garden dump' all over the formerly open, friendly, inclusive and platform neutral modding community under the guise of 'convenience' is no reason for GOG, Epic or anyone else to double down on it.
As for subscriptions for a "free access to a catalogue of games", that's simply not going to work for DRM-Free games as subscription based content by definition requires the store to deactivate access to content after the subscription ends, otherwise there's nothing to stop people subscribing for one day, grabbing the lot, backing them up then unsubscribing. So anyone who voted 'yes' for that basically is voting for GOG to become a DRM'd "Software as a Service provider"...
I feel a partnership with someone like Nexus Mods, having in built integration tools for both Galaxy and the website for Nexus mods would be a great way to give workshop functionality without locking it to GoG.
The subscription idea, I can't really see a way to give it added Value.
* Streaming. I'm not paying for the privilege of streaming from my own machine; And the ability to stream from a server, while fun and can be useful, requires a prohibitively expensive investment in infrastructure GoG can't really afford
* As AB2012 says, you can only do subscription access to a catalogue with DRM
* loyalty discount... sure I'd easily spend enough to recoup the cost... but its just tacky
* VIP Treatment. Not keen on a 2 tier system, and you'd just be a "blue tick" person
The only thing that I feel fits with what should be GoG's ethos is a "Supporters Subscription", like a Patron or "investor". The reward is keeping GoG going and growing. With the occasional "Insider" newsletter and such.
