In the meantime, RE: Doomsday - it could as well be an overkill, as usual the galaxy is our mutual testbed. Have you tried stopping it, though? I mean, it's now being built on a specific planet, and thus is somewhat under player control.. We're very open to further fine-tuning, but please make sure you have actually tried all the in-game options first.
I think if I were to suggest anything, it would have been a little more helpful that there were some hints to let us know we were in the middle of a game event and there was an objective. After the fact looking through some previous posts only now appears it was an idea from digger to unite to attack a common enemy in planet form. Problem was, only the people who made discoveries or knew anything kept it to themselves on how to stop it.
The 4 times I saw doomsday (later evaluating the damage I see it was more times he actually visited my area), there were only 2 other people I ever saw chasing it around to keep the damage at bay. It didn't seem to unite anyone except a few people that happened to be in the vicinity or had something at stake. Not that there was much time to think of doing anything else while being attacked, since stopping each incarnation was a very laborious 4 hour activity. In one session Doomsday flew by and attacked the same planets twice, and then came back another day and repeated the same route. All I can say is that the whole thing wasn't planned very well, especially while being subjected to the crippling play speed. Anyway, it was what it was.
