I think it was very well done, as all the fundraisers tend to be. Obviously a tonne of creative work went into it, not to mention the technical aspects that were probably a pain to get juuust right.
I don't have any real gripes, but I do have one other observation: the whole thing was huge, vast-feeling in fact. The speed boosts solved the practical problem of getting around, as did the many (many) warp signs but I always had the distinct impression that, while some of us were doing something, we were doing it in one small corner and the whole rest of the server was laying empty... it felt a little off, kind-of like when P or C run-down over time.
Other than that, I thought it was fantastic! Thank You to everyone who made it!
