More scenario filters and Extra achievments

[koa61]

This is just a small idea, but:
I really want to play some official-scenario (like Golden age or Who cares) like custom scenarios that only use the world lab and maybe some extra events or government actions so it would be nice if I could filter scenarios based on labs used when creating them.
Another idea: There should be an achievment for killing everyone except Greenland
And a question for devs: How/When did you realize that Greenland is so hard to infect/Was it planned?

Interesting request for the tags. We can look into adding this.

That achievement would be too easy

Greenland wasn't explicitly planned to be the difficult country, it just came out that way in the simulation and it seemed to work
