Sorry, I disagree. Dungeonmans is a perfect example of why Steam's Greenlight program works. As long a game is updated on a regular basis, I say bring em' on.

Edit: Not all Greenlit games are full priced.

Sure, but regardless of their quality (which can be quite spectacular, I agree), how do you solve the patching/autopatching problem on a DRM-free store like GOG?

And, for people such as myself with a variable internet connection, forced autopatching can become a game breaker. And yes, I know I can switch it off.

I'm o.k. with it, but there should be a system to prevent incidents like "Towns' to happen.

I would like to see early access on GOG. But only when a game reaches a certain point, where they have something playable and a serious roadmap and such.

Games like Divinity: Original Sin, Jagged Alliance: Flashback or Prison Architect are some titles that come to mind.
This way you can support the developer and with extra funds during the development stage the game can become better.
