50 colonists? That would attract more people than the 100 colonists and All Sciences in my opinion.
I think 100 colonists is good. The difference between 50 and 100 is really small from a strategy perspective imo. I wouldn't add a 50.
I think all science is a bit demanding and unappealing.
A middle ground maybe First banner upgrade
Without a doubt rule change to as soon as you gain control of your character is when the timer starts. That's a general speedrun rule. I understand the desire to get a good placement but you can easily restart if in a bad spot.
All Science is probably the closest thing that I could think of for a 100% category for this game. If anyone wants a new category on the boards post the video of your run here and I'll add it and verify it.
Can the latest version 0.8 be added? Also I recommend a new category be added- All achievements, involves setting up colonies in the new world, tropics and far east with their own science and production. Also 500 colonists is an achievement. Please and thanks!
I think 1000 colonists would be a good category, as it's a large part of the game (being an achievement) and is something that most people associate with Colony Survival
