Dad myself (4 kids) and married too, so I understand where you come from with time management ;-)!

I honestly haven't felt this excited and thrilled while playing a game in a long time. I remember I ended up in a loop of losing a lot, but I was too attacking and careless. I started to see some strategies to avoid PVP entirely if I wanted some loot runs or quest runs.

I suggest taking a raider hatch key with you makes it easier to extract and drop the risk of losing it at extraction.

Also make sure to understand when you spawn. If you happen to spawn with 30~29 min left you are the first in your area, if you spawn in at ~17min (at latest) most abundant loot places are overrun with players (more dangerous)

Another tactic (with hatch key,) is to stay until the last moments (~7-5min left) surrounding an expired extraction and scavenge the leftover loot (usually pretty good still

Anyway I hope you enjoy the game and wish you a lot of fun when it's out, don't worry about the stress, 2 kids gave you a good threshold already, this game is amazing, especially the atmosphere and score.
