Enebias: Personally, I'm getting this feeling (this is 100% speculation, of course): the installers will not be ditched, and I don't think there will be Galaxy-only games.
Yet, I'm also pretty sure that as soon as the client is officially out every non-old game will be provided thorugh it rather than with DRM-free installers, being
de facto Galaxy-tied for a certain period of time; once the updating and patching process is complete (or at least when it reaches a certain level of stability) everything will be packed up into an installer by the GOG staff.
I also get the feeling that things like this are more due to the devs' unwillingness to provide separate updates (see Age of Wonders) to save costs rather than on GOG's arbitrary decisions -though I don't doubt they would find such system quite convenient.
I'm quite sure that this aspect is also one of the main reasons that brought *everyone* to jump on the Steam wagon and lead almost the entire PC gaming into this revolting monopoly state.
Sometimes I wonder: how much is Galaxy a free choice by CDP, and how much a necessity for business? If nobody cares about you as long as you don't give them the same advantages the monopolist can provide... as always, that's an unfair battle.
And as I keep repeating to nausea, I still wonder why the EU still has not put limitations on Valve like they did with everyone else, since they are imo in clear violation of several basic principles stated by the TFEU. There is no need to provide particular proofs: just looking at their market share is more than enough.
