R8V9F5A2: Considering GOG's focus on older games I think the average GOG user doesn't mind waiting for a full release.
There are a number of reasons as to why GOG has relatively few of all indie games released on Steam, including the fact that many, if not most, of these developers have
no intentions of delivering their games DRM-free.
I'm only talking about games that has already been rejected by GOG, and that number is already well in the several hundreds. Voting for games that dev don't want to released here is a bit pointless, which is another reason why the wishlist doesn't quite work.
And in the case of the average GOG user being able to wait for a full release... Well, that's great, I don't mind doing that either, I can wait years if need be even. But if it's already been rejected, with a rare few select exceptions (Hi Huniepop!), you'll be waiting for that full release forever. I think forever is a little bit too long a wait.
Lifthrasil: NO, please! We don't need tons of shovelware here. There's kickstarter for backing good ideas and if you want tons of crap, there's Steam for that. On GOG I would like to have only running, finished and complete games.
There wouldn't be a tons of shovelware if only one game is released per week. Most of the time I'm assuming really good game would be released, but even if every single game released through this process was bad, at most we'd get one bad game a week extra, and that would hard make up a ton. In fact, nothing I said would indicate that we'd end up with nothing but terrible games. I'm pretty sure you didn't actually read what I wrote.
