Entertaining game, really no strategy and all luck
After reading many other user's reviews, it seems that most of the changes have already been stated. However, I'd like to put in my two cents.
The game is very random sometimes, I did an experiment with selecting parasite, removing all of the symptoms and put no transmissions.
However, the parasite I was using still spread, and while none of the transmission sources were selected, all nations shut down airports, borders, seaports, etc...
Not only that, while I realize it might be game breaking in some effect, but a country doesn't burn bodies for a parasite that causes no symptoms or harms the host..
It was just frustrating is all, and I have also experimented with other settings and found out that infection/alarm to your virus/and the spread of it is reasonably random.
Please change the percentile chances to be more based off skill than luck.
