It was tough when it first happened. That exact thing is what kept me out of online games for so long. What a waste was all that time and money spent on a game that now couldn't even be played. All those in game friends, gone.
Today I see COT coming together. The pieces are falling into place. I see a game not just with a new engine and better graphics, but also a unique and I think better approach. It's not COX2. It's more like, "How would we design it today with both fresh technology and the benefit of experience?"
I'm reminded that necessity is the mother of invention. Without the COX shutdown, there would be no COT.
So how about you? Do you find yourself becoming glad that COX was canceled?
