Even though I'm British (and Japanese...) and I liked them, I have two points to make.
1. Using the words "British" and "Proud" at the same time as asking for opinions is probably going to cause some political things to happen in this thread at some point, which will cause a lock. Perhaps saying this means it will come true, but who knows.
2. I hazard a guess that most of the people bothered enough to post on this forum aren't sports fans for a variety of reasons, given that they chose to spend their time playing this game or writing stuff on this forum instead of watching the Olympics.
On the subject of the Games themselves, I did watch them, but I was really shocked to see so much coverage for British athletes and so little by comparison for athletes of other nations. To me, it was pretty rude, and doubly so as some commentators are calling the Olympics a success for Britain based on the medal haul rather than the quality of the hosting.
On the other hand, I had fun watching the sports on offer and they seemed very well organised. It was nice to see a summer version of the Snowboard X, the BMX, as well as a very challenging mountainbiking course. The Canoe and Kayak white water events were also extremely entertaining.
