Most of those are small/single developer games.

Which speaks to other issues that GOG has with PR and/or other systems in effectively attracting (and keeping) independent developers.

Well Cities: Skylines is not a small developer game (medium developer perhaps, huge publisher)

I think it's more the DLC mentality.

Not that DLC is necessarily a bad thing nowadays (Rimworld does it well).

But DLC can also be abused to capitalise on gamers:

Predatory DLC (sorry Paradox you've painted yourself into this corner over the last few years) relies on metrics to monitor and inform future DLC. So I can comprehend why DLC-active games might not be on GOG - GOG only recently introduced proper bundle sales for DLC and even then it's not great. For Paradox it doesn't explain the greed of trying to sell CK2 complete for $100 - they are Trump in DLC gaming form.


I agree with this 100%.

Why are you asking for this money at checkout? If it is a charitable endeavour then set up a charity and elicit donations for that.

If the money is linked to the games you are selling at checkout, then check whether the money will be going to preserving the games the customer is actually buying.

Otherwise it's shady af.
