Cool to see RollerCoaster Tycoon 3 back here. :)

I concur that the main drawcard for me was the ability to buy a digital copy of some games I had already bought, including most of the games for which I had physical copies at the time, as well as those I thought I would never play again because I no longer have the firmware.
The close affiliation with CD Prjojekt RED that has yielded the most notable AAA games for Gog was a secondary consideration. (I haven't played past the intro of The Witcher II, for instance, since I was happier with the Aurora engine modification that the first game was since I found it to be a near-perfect mouse-only interface, meaning it can be played one-handed.)
Perhaps the problem is that people are exposed to games in their Interweb habits and then look to see if Gog has them. I come to Gog and look to see what is available here and choose whatever I feel suits me best at the time. I have no need nor desire to play "everything" and if I miss a few genuinely good games I'm not bovvered. (Apologies to Catherine Tate.)

It seems people are willing and eager to spend more to have less hassles: give them a single button to press that installs and configures their timesink so that they needn't concern themselves with all that mucky command-line legerdemain. Who cares if it's not perfectly optimized, as long as they can complain when it doesn't work out of the box? Apple has built a three-trillion dollar company by giving people convenience at eye-watering expense.
