Great spin off!
This was great, but I think the origional was better, because there was more to evolve your virus into.
A small sidenote: "A plane in Europe arrives in.... Europe.." ? Opps, perhaps you should have coded it so that planes don't arrive and land in the same country!
Infetive greenland is a bitch, unless you start off in it.. I did once, and before I got my infectivity level higher and infect a plane, the bastards died and I was contained. :(
