So you are putting forth that X2 > X1 despite (or because of) X-Y-Z/? I fail to see how that could be, given
the almost unanimous preference expressed for good Old Games by the patrons here, the failure for these new games to hit the bestseller list, and gog's complete lack of competition in pricing.
If X2 is current GOG resources dedicated to old games, and X1 is GOG resources dedicated to old games back in 2010, then yes, that is what I'm saying. That even though GOG is currently dedicating Y resources to new games, the resources they are using on getting older licenses are still more than they were a few years ago.
Whether the Y resources are spent wisely or not is a different subject, though FTL, Legend of Grimrock, To the Moon, Alan Wake's American Nightmare, Gemini Rue, Divinity 2, Botanicula, Blackwell Bundle and Hotline Miami have sold pretty well (according to the Best Selling list at least).
And even though we have all those complains, GOG had released 35 pre-2k games in 2010 and 36 games 10+ years old at date of GOG release, while so far in 2013 they have released 26 pre-2k games and 39 10+ years old. There are still 4+ months of releases ahead of us. If GOG releases 9 more pre-2k games, they will have released as many old games as they did back in 2010, and considering that in 2011 they've released 48 pre-2k and 47 pre-2k in 2012, I do feel we'll get at least 20 more pre-2k this year as well.
