You had meant for the high tech factions to attack in the latter game but i had Orion raids before my first winter.And because of excellent planning i simply got free Glitter tech level weapons.Those master quality 20 damage pistols are insane that early on.Not only did one of the early orion's one shot a colonist(lol) but then i collected the loot and had an easy early game.Id suggest tweaking their raid values Otherwise the high difficulty mid and late game raids are fun,dangerous and insanely rewarding if pulled off.
