Infectivity feels a little too strong. Especially rushing Love 2 which gives you a really, really fast start.
I was able to win (infertility ending, not lethal) on mega-brutal in just 190 days which should probably be a lot harder to do. Maybe it's a good idea too also disable gene selection. Some combinations can really break the balancing in custom scenarios.

Oh, and I should probably mention that balancing aside it was really fun to play! I actually used infertility as a symptom in one of my own scenarios and was thinking about a disease using it as a theme. Definitely going to keep an eye on this one in case you are planning any big updates.

Thank you for pointing this out. I'll be sure to change this.
Changed it :) I hope it's more challenging now. See the change notes for details.

Thanks a lot ^.^ It's my first try at building a scenario so I'm not at all surprised that it needs some polishing, hahahaha!!! I really appreciate the input.
