mrkgnao: I'll try to explain. probably unsuccessfully, with an example. Suppose GOG comes out tomorrow with five new games, all
with DRM. Would you also say: "people who want to buy DRM games can now buy them from GOG. GOG has the opportunity to make more money. People who don't want to buy DRM games are unaffected. What exactly is the downside?". My guess is that you wouldn't. I may be wrong.
The automatic assumption that the only reason people buy on GOG is because DRM-free is false. I, for one, care about other things (e.g. worldwide availability, fair and equal pricing, complete editions, game quality) no less and perhaps even more than I do about DRM-free. I do not subscribe to the notion that as long as GOG sells DRM-free games it can do anything it wishes and that would be fine by me. I myself do not want to promote the habit of releasing incomplete products and I find it annoying that a place I frequent daily does support it. It goes without saying that I will not buy such games. The question remains whether I want to have to see them on the screen day after day.
Fair enough. I agree that the In Development games are being over-promoted right now. I assume/hope that they will drop off the top of the page once the novelty wears off, or the next big thing comes along. EDIT: Look at that - I just checked the frontpage, and the In Development games have dropped from the top of the page. This is definitely better.
They only other point I'd like to make is this - I'm not sure it's 100% valid to call the In Development games incomplete or unfinished. I think GOG has chosen a perfect name for these games. They're In Development. The problem is, it's easy to get hung up on "1.0", when 1.0 is really an arbitrary target set by the developer.
Look at Terreria. Terreria released version 1.0 in 2011. By normal standards, it's V1.0 - it's complete. There have been several significant updates to Terreria, the most recent being released in 2015. The current version (1.3) is quite a bit different than 1.0. Improved engine, different end-games, more bosses and NPC's, etc. The Terreria developer gets credit for continuing to support their game after release, when perhaps the game wasn't actually complete at 1.0. Realistically, Terreria has been "In Development" for the last four+ years, but because the version number is > 1.0, that's OK.
Alternatively, look at Spacebase DF-9. I know this one isn't available at GOG, but it could be. It's even complete, right? Double Fine slapped a 1.0 on a half finished game and abandoned it. It's not a finished game by any stretch, but it's also not in development any more, so it could come to GOG and be sold as a finished product because it's got that snazzy 1.0 on it. I'd rather play Starbound than Spacebase DF-9 - it's a much better game, despite the fact that it's still "In Development".
As I see it, there is a class of game like Starbound and Project Zomboid that are always in development, and this is just an extension of GOG's product line. It's still curated - so far the In Development games appear to be games that are very playable in their current state. It's still DRM free.
