Probably we are lucky that we do not get the ad about making illegal copies as most DVDs.
As a software developer, I understand that the quality is a general problem in the industry these days (we have an entire operating system as an example, not only a game). But a game is about having fun and the quality can shift the decision to other things.
For example, I played GOTW (deity, PS3, as cristig) yesterday morning and I found a solution to finish in 2100 BC. In thew evening I checked the leaderboard and not only that my result was not there but I am no longer first as someone has a 2000 BC. So I played again and did the 2100 BC, asking myself if I should have put a movie in the PS3 instead of civrev. Today it is still not registered.
I play for fun, but thing like that can make me to play another game or watch a movie. I was considering posting the solution here, but I am afraid that this will spoil the game for other players more than will make someone for 2K have a reaction. After all I, know that writing a program for a leaderboard it is the most complicated piece of software and they could have easily done it right from the initial release.
So maybe I'll watch a movie next time. Or, as I saw also that with civ4 the patches from the community were better than the original, maybe we will see and open source civ sometimes.
