I concur with those who're saying that, if it's your first time playing, you should close the thread right now. The less you know the more you'll enjoy it. Maybe that's true for most games, but it's specially true for Kenshi. You'll understand why later.
On "powergaming"...
Is there anyone who doesn't "powergame"? The problem with Kenshi is that, once you know what to do, it's simply not challenging anymore, so you have to impose restrictions on your playstyle, either mechanical restrictions(like tweaking the economy/combat/troop formations, playing with zoomed in camera and other tricks I've posted about before) or "roleplaying" restrictions(solo/small squad, recruit only the same race, no prosthetics, etc.).
If you just care about roflstomping everyone without concern for challenge, that ironically makes you more of a roleplayer than the roleplayers.
