It is hard to say what people mean when they say GOG should "focus" on older classics. Does it mean they/you want GOG stop selling newer (indie, or whatever) games, or what? Do you really believe that would help getting more old classics to GOG than you are getting now?
"Focus" is admittedly pretty vague. I guess (and I've probably voiced this concern before, and perhaps received a response) sometimes I get the impression (let me emphasize that; it's an impression, certainly not fact) that GOG is almost working
to distance themselves from the fact that they still sell old games, and is now far more enthusiastic about promoting, discussing, or "distracting" us with newer titles and only DRM-free-ness (such as the latest Divinity game: we got an interview and a giveaway with that team, but I can't remember the last time we got an interview with an industry veteran like someone behind Tex Murphy or Little Big Adventure). That's what frustrates me, because I was initially attracted to this site because of what it brought to the table that other websites didn't: a living museum of gaming, with the best of the past available here. Of course we still get some of that - heck, System Shock 2 and some of the Wizardry titles - but at times I still feel like GOG is sort of saying "meh" to the desire for more good old games.
My hope was that GOG selling newer titles and showing publishers the positive sales results would bring even more fantastic, exciting good old games, but that doesn't seem
to have been the case. Half a year ago we were hearing about Take-2, LucasArts, or Microsoft being highly interested in coming aboard, and yet as GOG has grown, that deal seems to have collapse, which is very depressing to me.
Now of course my frustration should probably mostly be focused on publishers that are obsessed with Steam and/or DRM, and unwilling to bring their titles here. As expected, we don't really know what's going on behind the scenes, and while we obviously can't expect to be told much, that adds to my frustration.
So I'm pretty sure I haven't answered your questions, my apologies. I just need to vent about this on occasion. I want to see GOG kick things up a notch, kick a few doors down of IP holders, and come marching out victorious to the cheering crowds of point and click adventure lovers. Instead I feel like everyone is trying to force me to be enthusiastic about a mixture of Desura, the casual section of Target, and XLBA. I won't try to stop others from enjoying the indie titles here, but in the same way, I sometimes want to say what I want to see offered (as a customer).
