There appears to be an issue with gender RNG. Having all colonists in the same gender isn’t exactly great from the game play perspective. I am at game year 6 right now and the only Female colonist I ever had came as immigrant at very old age, she had only about 20-30 days before passing. Now I got 6 colonist and 2 dead from an old age.
I tried to edit the save games to alter genders but the file are protected by CRC of some kind making edit attempts next to impossible.
The change of getting 8 colonist of same gender in a row with a pure RNG is 1 out of 256
Had a few games with 5-6 females starting, but more rarely had 5-6 males in a row.
I know its randomly selected, but I’ve had lots of coincidences…
Guess its the luck of the draw and they usually balance out over time.
If you want more variety, save your game just before an immigrant arrives and if its a male just reload the game and you will get a female within 2 or 3 tries.
Its not really cheating if its correcting a bad imbalance in your immigrants female/male ratio’s
The saves are not encrypted, but saved in binary, making edits really difficult. Editing genders is prone to create bugs, but saving the game before a migrant arrives and reloading is a hack that works.
