I've got no specific objections to this game starting whenever you want, even if Ngoogol isn't finished, but the players have to be considered as well. Ngoogol is going to finish up after not too long anyway though, and I think collectively a bunch of players/hosts are looking at a busy time.
Because it looks like we'll have a new NOTW starting in a week or two as well, and maybe a couple small games starting. So if everything was starting at once I could see that being a problem, particularly the two large games - this one and NOTW XXXIX.
So really I don't know if getting this one going early, as in very soon, would be better or if that would make people more overwhelmed/less active. As the host you'll know what works best for this one anyway, and again don't worry about me then.
