My random two cents since I have not read anything:
I got my ass kicked by the Ratmen Rodeo; first mission out of the base.
I didn't take it too seriously (I'm hyper aggressive) but wow, gals felt really delicate and only six, ouch. Oh well, more meat for the meatgrinder!
edit: Just did another quick start... wow, what changed? Early game is significantly nerfed... barely made it through the first month (couldn't catch ANYTHING - all civvie vehicles - all the spawned missions were way outside the range of the Airbus - and then a mutant pogrom with six gals? Yikes...). Second month I catch up to a landed Raider ship... didn't even kill one and then promptly got exploded. I'm actually pretty turned off from this... basically watched the sun rise/set the first month (huge negative score and lost protection money) and then TPK on first mission.
Wow.
Hey Draco! I don't think its intended for the game to be super hard in the beginning, with .99. I was able to clear the early missions without much trouble, (no more than 20-30% losses per mission)... ie. Ratman Rodeos... etc.
And yeah, the Airbus' short legs makes it really suck. I missed about a missions a month the first 3-4 months due to its limited range. It made me wonder if a Central Asia start might not be the best as your limited range would have a greater chance of covering more land mass that way.
Hunting Bows are great for these early battles imo. Hide behind the Airbus and lob arrows over the top.
I don't think its possible at all to avoid a big negative score in the first month (and maybe a couple after that).
My big break came in the enemy's Base building wave that came in month two. I tackled a gunship with heavy losses but a nice haul of captured gauss. Then I threw two crews at enemy Frigates capturing two of them. (The nice thing about the Frigate, was the Trader crews didn't have any Power Armor troops). With the sales of these three craft I boosted to about 10 million, and I expanded out the base enough to handle my full complement of 15 brainers. I think with these gals cranking through techs I'm safe from those big negative point hits.
Also, I think Mutant Pogroms are delayed until after you research Mutant Alliance, so it might be worth putting those off early.
