Mr. Meier,
It is an honor to post on your thread, sir! Your wonderful, creative work in the computer gaming industry has brought so much joy and happiness to millions of people. I can't tell you how many hours of pure fun I have had playing and modding Civilization 4 alone.
I completely understand the reasons behind creating a Civilization Network game that will live in the incredibly popular social networks that are all the rage these days. It doesn't take much brain horsepower for the average person to realize that this will be wildly successful. Another clever and smart business model from Sid Meier!
But I must also say that personally, and I am not alone, I do not participate in these social networks beyond trying them out here and there, and my hope of hopes is that we will also see a Civilization 5 at some point, for the PC. Please don't forget about us hardcore grognards out here!
Having said all that, I would certainly dust off my Facebook account to play a game created by Sid Meier, because there is no doubt it will be a treat. Perhaps Civ Networks will lead us all into social networking, who knows?
Keep up the great work, you, sir, are a rockstar.
